I think that future W3C XML query language (XQL ?) will be based on XPath,

XPath also used in XSLT and in XPointer, so it's good to reuse it in XQL
too.

The eXcelon XML Data Server developers
switched from XQL to XPath + XSLT + their proprietary XML-Update language
in their new beta, they still supporting for backward compatibility older
W3C-QL '98 XQL.

They suggesting to use XPath like "WHERE" clause in SQL and XSLT like
"SELECT", "SORT BY" and "ORDER BY" ...

We also need let to know W3C that there is need in standard XML UPDATE
language,
or at least enter this capabilities into future W3C XML Query Language

Summary:
    I think we should start implementing XPath, because for sure future
W3C XML Query Language will be based on it.
