This is so interesting!

If by Microsoft prototype you mean 
http://131.107.228.20/xquerydemo/

Insert / Delete / Update 

this is really neat stuff! 

What is the status of UPSERT word? 
Is there any paper on W3C website that 
contains this word, or this is MS-only thing?

Also, I tried searching for the word 'update'  in the 
http://www.idealliance.org/papers/xml2001/papers/html/03-01-04.html
but it seems there is no such word in the document.

Maybe you're referring to some other Jonathan Robie's 
XML 2001 talk?

Note that XQuery is planning on adding update syntax and semantics (for
an example see the syntax in the Microsoft prototype and Jonathan
Robie's XML 2001 talk) and several people in the working group are
working on it. It probably won't be part of 1.0 though for not delaying
1.0 even further.

Best regards
Michael
