XQilla will save changes to documents back to the filesystem. I agree 
that you could cause a lot of damage, but no more so than a bad use of 
"sed" or any other command line file manipulation tool. The XQilla 
command line tool requires a switch to be specified before it will parse 
XQuery Update - so you won't be able to run an updating expression by 
accident.

If you are worried about overwriting the original document, you can 
always use a "transform" expression and still work with the update paradigm:

I think that XQuery Update will find a lot of use cases where XSLT would 
have been used before - I'm sure many people will find the update 
paradigm easier to work with than the transform one for simple document 
modifications.

I'd love to implement XSLT 2.0, but it's not my top priority now. We're 
already a large part of the way there because of the XPath 2.0 engine. 
Of course if anyone wants to offer to do this, I'd be delighted to help 
them along :-).
