[xsl] XML schema: require a descendant?

I guess this might be a bit off-topic for an XSLT list, but in any case it's related to XPath.

In my data (simplified here):


I want at least *one* of the <sense> nodes to contain <term>, <persName>, or <title>. But it only needs to be in one of them, thus <entry> needs at least one descendant from the above three tags.

Is there a way of writing this into a DTD or schema?
