Sorry, you are right, of course. I've picked it up from one of the papers of
the QL conference -

Not to mention the chances of unifying XPointers and XQL - technically a
sound notion (even if the "XPointer" version is limited to selecting a
continuous portion of the tree), but highly unlikely.

I find it disturbing that something such as XML which is about as "new
technology" as you can be is already suffering from so much
backward-compatibility and "historical reason" warts. XSL which has never
even seen version 1.0 is already showing these symptoms!
