sure :)

But this by far is not an equivalent of what I described. It is 
insufficient.

... and this is too complex and too long for my taste.

Exactly.

Exactly! :)

Why? Well, it's very common in my (and in many others I would think) 
transformation to say thinks like "All variablelist elements containing 
nothing but an optional element title followed by one or more 
varlistentry elements are translated to simple dl(dt,dd)+ lists".

In any case:


I think that very simple things like contains(title?, varlistentry+) 
should be very simple to express in XPath.
If I'm still not missigng something obvious:
Perhaps something like a content-model() function will be available as 
extension or in XSLT2?
