Re:  relative . not working in complex xpath
"." within a predicate refers to the node that the predicate
is being applied to, so the context item for ./xs:extension is the same as
the context node for @name.
If you're using XSLT you can often get
arround this using the current() function. In pure XPath 1.0, join queries
like this are difficult and not always possible. Switch to XPath 2.0 or
XQuery if possible.
