The MathML reference (&lt;mathmlref&gt;) element is used to refer to a
non-DITA XML document containing MathML markup in order to use the
markup by reference. The reference must be to a MathML &lt;math&gt;
element. The reference may be a URI that addresses an XML document
whose root element is a MathML &lt;math&gt; element or a URI that
addresses and XML document and a fragment identifier that is the XML

ID of a &lt;math&gt; element within the document.
NOTE: To reuse MathML markup stored within a DITA topic, use a normal
content reference from the &lt;mathml&gt; element.

The reference may be direct, via the @href attribute, or indirect,
via the @keyref attribute. For key references, only the key name
should be specified. Any fragment identifier for specifying the ID of
the &lt;mathml&gt; element to use must be specified as part of the key
definition's @href value.

Example: For example, to refer to the &lt;math&gt; element
with the @id value "equation-02" within a larger document using a key
reference, you would define the key like
so:

&lt;keydef keys="mathml-equation-02" href="math/mathml-equations.xml#equation-02" format="mathml"/&gt;

You would refer to this key using just the key name:

&lt;mathml&gt;
  &lt;mathmlref keyref="mathml-equation-02"/&gt;
&lt;/mathml&gt;

The MathML should be processed and rendered as though the
&lt;m:math&gt; element had occurred directly in the content of the
containing &lt;mathml&gt; element.

The MathML container (&lt;mathml&gt;) element contains inline MathML markup or
references to MathML elements stored in a separate non-DITA XML
document.

The purpose of this element is simply to contain MathML markup. It is
not intended, by itself, to convey the semantic of "equation". Rather,
it simply serves to hold one of many possible ways that the content of
an equation may be represented. The companion equation domain provides
elements for representing equations semantically, independent of the
format of the equation content.

The MathML markup must have a root element of "math" within the MathML
namespace "http://www.w3.org/1998/Math/MathML".
