-Should we allow variable references in the expression? The current patch for mozilla does allow any toplevel variable and parameter in the stylesheet, but it might be a tough requirement on other XSLT engines. Especially since that allows any parameter to reference any other parameter so evaluation order is tricky.
 Should we allow any XSLT functions in the expression? document() seems useful, but it seems tricky to maintain the invariant that generate-id() should produce the same string for the same document.
