[xquery-talk] XHTML namespace and doc() function

Wed Jul 7 14:47:53 PDT 2004

The fn:doc() function does not (or at least should not :-)) use the
default element namespace to resolve relative URIs. It uses the base
URI.

So it looks like a bug in the XQuery engine that you are using.

Best regards
