     Sorry for my delay in responding - I've been on vacation.  Xalan-J 
2.3.1 treated the expression // as equivalent to 
/descendant-or-self::node(), but only the latter is a syntactically 
correct XPath expression.  You should be able to use the latter with the 
Xalan-J 2.7 Interpretive processor.

Thanks,

Henry
