multiple xml namespaces

I have an xml document with nested fragments, each with their own default
namespace. My xquery select statement fails because I can only declare one
default namespace. Has anyone encountered this issue before? Am I
overlooking something?

If the XML has several default namespaces then with your XQuery you
cannot use the declare default namespace directive for all of them. You
can however declare your own prefixes for those namespaces and use those
in XQuery expressions like in this example:
DECLARE @.x XML;
SET @.x = '<foo xmlns="http://example.com/ns1">
<bar xmlns="http://example.com/ns2">
<foobar xmlns="http://example.com/ns3">foobar</foobar>
</bar>
</foo>';
SELECT @.x.query('
declare namespace pf1="http://example.com/ns1";
declare namespace pf2="http://example.com/ns2";
declare namespace pf3="http://example.com/ns3";
pf1:foo/pf2:bar/pf3:foobar
');
