Hi

new update - only doc

+    <para>
+     Only XPath query language is supported. PostgreSQL doesn't support XQuery
+     language. Then the syntax of <function>xmltable</function> doesn't
+     allow to use XQuery related functionality - the name of xml expression
+     (clause <literal>AS</literal>) is not allowed, and only one xml expression
+     should be passed to <function>xmltable</function> function as parameter.
+    </para>

Regards

Pavel
