in XSLT patterns you can have predicates, like "*[predicate]" , which 
can make use of any axis. Would you limit the content of these too?

I understand your motivation (also looking into the thread with Jirka) 
and agree that it would be useful. But maybe it would need to be even 
more restrictive than xslt patterns.
