Example
This section is non-normative.
The following code sample shows how a
<numcharref> element can be used to tag
the numeric character reference for the a-acute Unicode
character:
<p>Numeric character references represent characters from the Universal
Character Set (UCS) of Unicode. They are used to reference characters that
cannot easily be directly encoded in a document, such as a copyright
symbol. When a markup-aware processor encounters a numeric character
reference, for example, <numcharref>225</numcharref>, it renders the
reference as the Unicode character that it represents: lower-case a with acute.</p>
