I don't buy this explanation, David.  Sure, no context node is  
defined in user-defined functions per se.  But Robert explicitly  
establishes a context node in the function:

   doc(...)/*/
        (
          ...
        )

This means that the attribute axis steps like @id, @label should work  
fine in the parentheses.

The error message that Robert receives seems weird to me (shouldn't  
happen).

Cheers,
