XQuery as a general data processing language WAS: XQuery and Web 2.0

 XQuery as a general data processing language WAS: 
	XQuery and Web 2.0
Well...ok....what about something like a non proprietary LINQ done  
properly?

It would still suffer 'the impossible to optimize'  issue but at least  
it would open up the libraries of the programming environment you are  
working with pretty seamlessly, would integrate nicely with the  
programming environments a lot of people care about today, and I am  
guessing that the actual query part that goes out to the indexed data  
store can be optimized. I understand it might not be easy to  
'identify' that part of the query ...perhaps that is what you mean  
with 'impossible'?

Personally I am really trying hard to use XQuery in my day to day  
development activities (I do like the language a lot) and the only  
thing I can conclude from my daily experience is that for most things  
at hand it introduces as much issues as it solves.

That means
(1) I am not using it properly and/or
(2) the language is still missing features and/or
(3) it is not the right tool for my job.

Show us normal mortals writing the less fancy apps of the web (and I  
tend to think that is were your eventual main stream adoption of the  
language will have to come from, as there are a lot of us) how to use  
XQuery.

I think I am entitled to claim I know the language good enough...but I  
just can't figure out how to put it to use.
