You know I think you are right -- I could not find a way to do this other than using a different mechanism (e.g. [count(role)!=0]) than the wildcard.

BUT there is no way to specify wildcards like *. <c:set var="pred" value="*" /> <x:forEach select="$doc//employee[role=$pred]" > appears to result in a select like "$doc//employee[role='*']" which is not correct. I've dug through the archives and this is not found, nor any clear mention in the spec. It smells like a valid bug/missing but necessary feature. I'll give it a couple of days before I log something.
