Example

The following example declares that the <bo> element is conceptually equivalent to the markup construct <hi rend='bold'>, and that an external definition of this concept is available from the URI indicated

<elementSpec ident="hi" mode="change">
 <equiv name="BOLD"/>
 <desc>bold typography</desc>
 <attList>
  <attDef ident="rend">
   <valList>
    <valItem ident="bold"/>
   </valList>
  </attDef>
 </attList>
</elementSpec>
<elementSpec ident="bo" mode="add">
 <equiv name="BOLD" uri="http://www.typesrus.com/bold"/>
</elementSpec>
Note
The mimeType attribute should be used to supply the MIME media type of the filter script specified by the filter attribute.
