I could rely on DTD validation, but I don't think I should. My template says what it matches, and thus states what it can handle: no matter what which version of which spec/schema(DTD etc) says. It can handle this type of content model, nothing more. And if a future version of the schema allows for an extended content model, there will be no problem with validity in the oputput. > If validation is not an option it's often simpler to match on the > simpler * case but then have > <xsl:if test="not(varlistentry)">...

<t:template match="variablelist[]">
<t:if test="title">
<t:element name="h{count(ancestor::*)}">
<t:value-of select="title"/>
</t:element>
</t:test>
<dl>
<t:apply-templates/>
</dl>
</t:template>
<!-- quirky -->
<t:template match="variablelist[]/title"/>In [], picture either a very long XPath1.0 thingy, or an elegant, short content-model description :) But beware; sure there are many different ways to handle this, and none of them *requires* what I propose. But it would make some things simpler.
