As a random 2p.

I think Xquery is simpler then xslt by any measure...yes I think that
initially Xquery as it *was* being specified could have found themselves
with a dead end language, ...but actually its super simple; w/o sounding
too sugary I think that the existing W3C group responsible did the
language justice....and we will feel its impact at some later point when
we need to do some real work on data...XSLT is lightweight fun, airy and
light....though I wouldn't want to apply it to anything but content
related tasks currently; by comparison Xquery is an industrial strength
solution to many *hard* data problems.

More 2p.

XML Schema is dead on arrival, always was dead.... it never the W3C had a bad day, so what, lets get over it and
use RELAX NG and move on, or at the very least translate to XML Schema
at the last moment. 

On the other hand XPATH, XSLT and I have no doubt XQUERY will continue
to be successful.

People prefer other languages because they don't want to learn 5
languages to achieve something, XSLT is good at transforming xml into
other xml...which apparantly is vastly useful....possibly the work of
partial schemata in motion.

To me XSLT has benefited from the wild success of XPATH, we all get
it....though I cant understand why XPATH hasent been extended to an xml
update language....why make data when we have no facility to update it ?

Its rare for version 2.0 of anything to live up to its name, so why not
submit your suggestions to W3C before Feb 15th ?
