It's perhaps worth noting that XPath 2.0 has the "default namespace
for element and type names" as part of the static context, and thus
settable by the host language. A future version of XML Schema that
used XPath 2.0 could easily state that the default namespace for
element (and type) names was the same as the target namespace of the
schema. Whether this would be desirable in the face of unqualified
locally declared elements is another matter...

Cheers,
