<mathmlref>
Use the <mathmlref>
element to reference a non-DITA XML document
that contains MathML markup. This element enables you to use the markup by reference.
<math>
element. The reference can
be one of the following:<math>
element as the root element<math>
element within the document Processors SHOULD process the MathML
as though the <m:math>
element had occurred directly in the content
of the containing <mathml>
element.
The reference can be direct, using the @href
attribute, or indirect, using
the @keyref
attribute. For indirect referencing, specify only the key name.
Specify the ID of the <mathml>
element
as part of the value for the @href
attribute on the key definition.
<math>
element with the
@id
of "equation-02" within a larger document using a key reference, you
would define the key in the following
way:<keydef
keys="mathml-equation-02"
href="math/mathml-equations.xml#equation-02"
format="mathml"
/>
You
would refer to this key using just the key
name:<mathml>
<mathmlref keyref="mathml-equation-02"/>
</mathml>
