Finally, we managed to reproduce & track down the odd & severe 
behaviour/bug of eXist-db, which changes the order of elements in XML 
documents and breaks the document in other ways, too.

Bad news: The problem exists (at least) in eXist-db 1.2.0 
rev7236-20080115.
Good news: The problem does not exists anymore in eXist-db 1.2.4 
rev8072-20080802 or at least I am not able to reproduce it with my 
example code. Maybe it has been fixed on purpose?!?

Anyway, I have enclosed a test database (XML document) and a test XQuery. 
Put the XML document to the database (/db/testdb.xml) and change the 
owger&group access rights of the document to "guest" & "guest". Finally, 
execute the XQuery in XQuery Sandbox and see what happens to the "id" 
attribute of the <researchareas> element. Yes, it's has disappeared and 
the value of that "id" attribute has shifted between the first and second 
<researcharea> element.

If I will move the <researchareas> element before the <projects> element 
and do the update, then everything works fine.

I was not able to figure out what is the reason for this odd behaviour, 
but I would sure like to know. Like I said, eXist-db 1.2.4 works fine with 
my test case.

Kind regards
