Inline XBRL is a standard for embedding XBRL fragments into an HTML document. The objective is to provide documents which can be viewed in a browser while making use of XBRL tags which can be processed automatically by consuming applications. This specification defines the syntax for such documents and how the syntax maps into an XBRL instance.

There is a clear need to publish financial and business information both in human-readable and machine-readable formats. With the growth of interest in using the [XBRL 2.1] standard to transmit information in a machine-readable format, it has become necessary to create an extension to the [XBRL 2.1] standard which will tie the machine-readable data to co-existing human-readable formats.
Inline XBRL provides a mechanism for taking financial and business information formatted in HTML, the universal language for web browsers, and adding to it hidden metadata which can be used to construct a machine-readable copy of the same information. That extracted, machine-readable, information is fully compliant with the [XBRL 2.1] standard and can be used by regulators and other consumers of financial information.

This specification defines an XML namespace to be used for XML components
described herein. It is http://www.xbrl.org/2008/inlineXBRL.
This specification uses a number of namespace prefixes when describing elements and attributes. These are:
| Namespace prefix | Namespace name |
|---|---|
| ix | http://www.xbrl.org/2008/inlineXBRL |
| ixt | http://www.xbrl.org/2008/inlineXBRL/transformation |
| link | http://www.xbrl.org/2003/linkbase |
| xbrli | http://www.xbrl.org/2003/instance |
| xl | http://www.xbrl.org/2003/XLink |
| xlink | http://www.w3.org/1999/xlink |
| xml | http://www.w3.org/XML/1998/namespace |
| xsi | http://www.w3.org/2001/XMLSchema-instance |
The Inline XBRL Document Set is a group of one or more Inline XBRL Documents which when comprising sufficient metadata results in one or more Target Documents when transformed according to the mapping rules prescribed in this specification.
An Inline XBRL Document is a well-formed XML document containing both Markup Elements and Inline XBRL Elements and which MAY contain certain other elements as defined herein.
Within an Inline XBRL Document, the Inline XBRL Elements are interspersed between or nested within Markup Elements, in such a way that the value of each XBRL fact may be displayed by a browser.
An Inline XBRL Element is any element defined by this
specification with a namespace name which has a value of
http://www.xbrl.org/2008/inlineXBRL.
Each one of the Inline XBRL Elements in an Inline XBRL Document represents a different component of a Target Document. In general, each Inline XBRL Element takes the same content model as the matching component of the Target Document, except as set out below. The following Inline XBRL Elements are defined in this specification:
| Name |
|---|
ix:denominator
|
ix:exclude
|
ix:footnote
|
ix:fraction
|
ix:header
|
ix:hidden
|
ix:nonFraction
|
ix:nonNumeric
|
ix:numerator
|
ix:references
|
ix:resources
|
ix:tuple
|
A Markup Element is an XML element which does not have its namespace name listed in Section 2.3.
The following attributes are defined in this specification:
| Name |
|---|
arcrole
|
contextRef
|
decimals
|
escape
|
footnoteID
|
footnoteLinkRole
|
footnoteRefs
|
footnoteRole
|

A Target Document is the XBRL-valid XBRL instance document represented by metadata in the Inline XBRL Document Set.
An XBRL instance document is XBRL-valid if it can be validated as described in [XBRL 2.1].
An Inline XBRL Document Set
can be used to define multiple Target
Documents by setting the
target attributes on certain Inline XBRL Elements.
For each unique value of the {target} property on such Inline XBRL Elements there MUST exist a Target Document containing all the XBRL facts and [XLINK]-specified relationships which are required by the mapping rules prescribed in this specification for the Inline XBRL Elements with that value of the {target} property.
A Conformant Processor is a processor which transforms an Inline XBRL Document Set according to the mapping rules prescribed in this specification.
A Validating Conformant Processor is a processor which transforms an XHTML Inline XBRL Document Set according to the mapping rules prescribed in this specification and rejects all other input.
An XHTML Inline XBRL Document Set is an Inline XBRL Document Set that is:
in conformance with the rules described herein; and
composed only of Inline XBRL Documents that
html and a namespace name of
http://www.w3.org/1999/xhtml; and
It should never be necessary for a Conformant Processor or a Validating Conformant Processor to access the DTS of the Target Document whilst processing. Whether it does so will depend upon the design of the processor.
The processing of Inline XBRL Documents depends on [XML], [XML Names] and [XML Base].
The normative copy of the XHTML + iXBRL Schema is defined in [Inline XBRL Schema].
For convenience, a non-normative version can be obtained at http://www.xbrl.org/2008/inlineXBRL/2010-01-28/xhtml-inlinexbrl-1_0.xsd.
The ix:exclude element is used to encapsulate
data that is to be excluded from the processing of ix:footnote or
ix:nonNumeric elements, and has the following
properties:
<ix:exclude >
Content: ( any element | any text node )* </ix:exclude>
|
The purpose of the ix:exclude element is to
prevent text content from being included in the {footnote value}
property of ix:footnote or the {value}
property of ix:nonNumeric. It has no other use.
The ix:footnote element represents the
link:footnote element, and has the following
properties:
<ix:footnote
any attribute with a namespace name which has the value arcrole = anyURI footnoteID = ID footnoteLinkRole = anyURI footnoteRole = anyURI title = string > Content: ( any element | any text node ) + </ix:footnote>
|
|
| Property | Representation |
|---|---|
| {arcrole} |
The actual value of the
arcrole attribute or, if absent,
http://www.xbrl.org/2003/arcrole/fact-footnote.
|
| {footnote id} |
The actual value of the
footnoteID attribute.
|
| {footnote link role} |
The actual value of the
footnoteLinkRole attribute or, if absent,
http://www.xbrl.org/2003/role/link.
|
| {footnote role} |
The actual value of the
footnoteRole attribute or, if absent,
http://www.xbrl.org/2003/role/footnote.
|
| {relevant content} |
The content of the ix:footnote element,
excluding all nodes which are descendants of a descendant
ix:exclude element and replacing any descendant
Inline XBRL Element with its
own child nodes.
|
| {footnote value} | The {relevant content} property, resolving the actual value of any relative URIs as defined in section 12.4.1 of [HTML]. |
| {other attributes} | The set of attributes which have a namespace name which does not have no value. |
| {other attribute value} | For a given attribute in the {other attributes} property, the actual value of that attribute. |
| {title} |
The actual value of the
title attribute.
|
The lack of restriction on the child nodes of
ix:footnote allows Inline
XBRL Elements to be nested. This can be used, for instance, to allow
a number embedded in a paragraph of text to appear in the Target Document both as part of a footnote
and, separately, as a numeric item.
The ix:exclude element can be used to exclude
arbitrary data from the {footnote value} property of
ix:footnote. This allows, for instance, page header information
to be excluded from a paragraph which crosses page breaks. The
ix:exclude tag does not preclude its own descendant
elements from being processed elsewhere.
For each ix:footnote element in the Inline XBRL Document Set there
MUST NOT be any other
ix:footnote element with the same {footnote id}
property.
The ix:footnote element MUST
have an xml:lang attribute in scope.
For each element N in the {footnotes}
property of a given Inline
XBRL Element F, there MUST exist in
the Target Document identified by
the {target} property of F a footnote resource n
with relationship r from the XBRL fact f
which satisfies the applicable mapping rules defined by this specification for
F, where the relationship r is defined by a
link:footnoteArc element (with
xlink:arcrole attribute equal to the {arcrole}
property of N) within an
xlink:footnoteLink element (with
xlink:role attribute equal to the {footnote link
role} property of N), such that:
xml:lang in scope for n shall be
equal to the value L of xml:lang in scope for N;
xlink:role attribute of n is equal to
the {role} property of N; and
xlink:title attribute of n is equal to
the {title} property of N.
The ix:fraction element denotes an XBRL
fact which is an element of type, or
derived from type, fractionItemType; and has the
following properties:
<ix:fraction

It is common to include formatting in displayed numbers, such as group separators, which would not be valid in the Target Document. Inline XBRL uses Transformation Rules to transform such items into values that will be valid in the Target Document.
The ix:nonFraction element will either satisfy
the validation rules for a given Transformation Rule or it will, in its
un-transformed state, be capable of validation against the DTS for
the Target Document. Both these
conditions are covered by the requirement that the Target Document be XBRL-valid.
The display of numeric non-fractions in the Inline XBRL Document will often differ from the form in which those items are incorporated into the XBRL Instance. In financial statements, this is commonly done to allow numbers to be scaled and presented to the reader in thousands, millions or billions. Similarly, a percentage which might be displayed as an integer will often be incorporated into the XBRL Instance as a decimal.
Inline XBRL provides a transformation mechanism that allows this treatment to be preserved in the Inline XBRL Document.
Where the scale of the displayed value in the Inline XBRL Document is different to
that used in the XBRL Instance, the
ix:nonFraction element is given an
scale attribute to indicate the required
scaling value. For instance, if the Inline XBRL Document displays a value
in units of thousands, it will be necessary to multiply the value of the
ix:nonFraction by 1,000 to determine the correct value to be
included in the XBRL Instance, and the
scale attribute is used to establish this.
The value of the scale attribute shall be the
appropriate scale factor (for instance, 1,000 in the previous example)
expressed as an exponent of ten. Thus, if it is necessary to multiply the
tagged value by 1,000 to determine the correct value to be included in the XBRL
Instance, the value of the scale attribute
shall be 3.
Negative values are indicated by including a
sign attribute.
ix:nonFraction
The
ix:nonFraction element MUST
have name, contextRef and
unitRef attributes.
The
ix:nonFraction element MUST

|
| {relevant content} |
The content of the ix:nonNumeric element,
excluding all nodes which are descendants of a descendant
ix:exclude element and replacing any descendant
Inline XBRL Element with its
own child nodes.
|
| {value} |
If the escape attribute is true then the
escaped representation (having first resolved the actual
value of any relative URIs as defined in section 12.4.1 of [HTML]), otherwise the concatenation in document order of
all descendant text nodes, of the {relevant content} property.
|
Certain XBRL items, such as those of
type xbrli:booleanItemType,
xbrli:dateTimeItemType and xbrli:timeItemType
(amongst others) have content constraints which may not be met when displayed
in the Inline XBRL Document.
Inline XBRL uses Transformation
Rules to transform the items as displayed into values
that will be valid in the Target Document.
The ix:nonNumeric element will either satisfy
the validation rules for a given Transformation Rule or it will, in its
un-transformed state, be capable of validation against the DTS for
the Target Document. Both these
conditions are covered by the requirement that the Target Document be XBRL-valid.
The lack of restriction on the child nodes of
ix:nonNumeric allows Inline
XBRL Elements to be nested. This can be used, for instance, to allow
a number embedded in a paragraph of text to appear in the Target Document both as a non-numeric
item and, separately, as a numeric item.
The ix:exclude element can be used to exclude
arbitrary data from the {value} property of
ix:nonNumeric. This allows, for instance, page header information
to be excluded from a paragraph which crosses page breaks. The
ix:exclude tag does not preclude its own descendant
elements from being processed elsewhere.
ix:nonNumeric
The
ix:nonNumeric element MUST
have name and
contextRef attributes.
There MUST exist an
ix:tuple element in the Inline XBRL Document Set with a
{tuple id} property which has a value matching the {tuple
reference} property.
There MUST exist an
xbrli:context element in the Inline XBRL Document Set for which
the actual value of the
id attribute is equal to the {context reference}
property.
If the format attribute is present, the {value}
property MUST be valid in accordance with
the {format input type} property.
If the format attribute is present, the
{format} property MUST match the expanded name
implied by the value of the name attribute of a
signature element in the relevant Transformation Rules Registry.
If the id attribute is present, the {id}
property MUST NOT match the {id}
property of any other element in the Inline XBRL Document Set.
For each token in the {footnote references} property there
MUST exist an
ix:footnote element in the Inline XBRL Document Set with a
{footnote id} property which has a matching value.
For each ix:nonNumeric element, there
MUST exist in the Target
Document identified by the {target} property an
element which has the following XML properties:
The element MUST have attributes with the following properties:

The value of the
contextRef attribute MUST
be equal to the value of the id attribute of an
xbrli:context element in the Target Document which is
s-equal to the {context definition} property.

| Property | Representation |
|---|---|
| {value set} | All children. |
ix:resources
The
ix:resources element MUST
be a child of the
ix:header element.
There MUST be at least one

ancestors with that namespace name and, if the {tuple id}
property is present, all elements for which the
{tuple reference} property is equal to the {tuple id}
property of the current
ix:tuple element.
|
| {tuple content} | The set of Inline XBRL Elements in the {apparent content} property, such that each element has a unique {tuple order} property. |
The display of tuples in the Inline XBRL Document will often differ from the form in which they are structured within the XBRL Instance. Inline XBRL has mechanisms to provide for both the correct ordering of tuple content and for the association of tuples with their children where cross-nesting or the need to prevent the display of particular children would make this otherwise difficult to achieve.
Where the requirements of the display model do not allow what would normally be
the children of the tuple to be nested within that tuple, an
tupleID attribute is used to associate a
tuple with its children.
The ordering of children in the Target Document is enforced through the {tuple order} property.
The following examples illustrate ordering and cross-nesting of tuples:
Inline XBRL markup, showing tuples displayed out of order.
Resulting XBRL instance.
Inline XBRL markup, showing hidden tuple in header and children of different tuples sharing the same table rows.
Resulting XBRL instance.
Inline XBRL supports Inline XBRL Documents which include duplicate XBRL facts. Because this may result in invalid Target Documents it is necessary to remove duplicate elements where these occur in the {tuple content} property.
A corresponding validation rule requires that such duplicate
elements be semantically identical. Because this specification
does not require the use of the DTS, the Validating Conformant
Processor enforces a potentially more restrictive literal equality by
comparing the Whitespace Normalized Values.
The Whitespace Normalized Value of an element is the
normalized value as defined in [XML Schema Structures] of that element and its attributes and determined
as though the value of the whiteSpace facet were
collapse.
ix:tuple
The
ix:tuple element MUST
have a name attribute.
The element MUST have one or more
ix:fraction, ix:nonFraction,
ix:nonNumeric or ix:tuple descendants or have a
tupleID attribute, unless it has an
xsi:nil attribute with the value true.
The {target} property of the
ix:tuple element MUST be
equal to the {target} property of all elements in
the {tuple content} property.
All elements MUST have an
order attribute if and only if they are
members of the {tuple content} property.
Each element in the {tuple content} property with the same {tuple order} property MUST have the same Whitespace Normalized Value.
For each ix:tuple element in the Inline XBRL Document Set there
MUST NOT be any other
ix:tuple element with the same {tuple id}
property.
For each token in the {footnote references} property there
MUST exist an
ix:footnote element in the Inline XBRL Document Set with a
{footnote id} property which has a matching value.
If the id attribute is present, the {id}
property MUST NOT match the {id}
property of any other element in the Inline XBRL Document Set.
If the ix:tuple element does not have an
xsi:nil attribute with the value true then there
MUST be at least one element in the {tuple
content} property.
If the ix:tuple element has an
xsi:nil attribute with the value true then there
MUST be no elements in the {tuple content}
property.
The ix:tuple element MUST
NOT directly or recursively form part of the {tuple content}
property of any ix:tuple element in
the {tuple content} property.
There MUST exist an
ix:tuple element in the Inline XBRL Document Set with a
{tuple id} property which has a value matching the {tuple
reference} property.
For each ix:tuple element, there
MUST exist in the Target
Document identified by the {target} property an
element which has the following XML properties:
The element MUST have attributes with the following properties:
id
|
The value of the id attribute is equal to the
{id} property, if present, otherwise the attribute
must be absent.
|
| {other attributes} | For each of the attributes in the {other attributes} property, the value is equal to the {other attribute value} property. |
A Transformation Rule is a set of instructions which when applied to the schema normalized value of a given type outputs a value in a format which when included in the Target Document will be XBRL-valid.
The set of Transformation Rules is defined in one or more Transformation Rules Registries, one of which is the Specified Registry.
A Transformation Rule MUST NOT output a negative numeric value.
A Transformation Rule MUST NOT output a scaled numeric value.
The type identified by the value of the
type attribute of the
input element defined in a Transformation Rule MUST
NOT allow negative numeric values in its value space.
The Transformation Rules Registry is a registry operated in accordance with [REGISTRY].
Each Transformation Rule is defined as a function in accordance with [XBRL Function Definitions].
The normative copy of the Specified Registry is defined in [Inline XBRL Transformations].
A Conformant Processorand a Validating Conformant Processor MUST support all the Transformation Rules defined in the Specified Registry.
The following non-normative list summarises the Transformation Rules defined in the Specified Registry:
