There are at least two reasons for this. The XQuery langauge is still 
evolving, though it has become relatively stable, and different 
implementations support different Working Drafts of XQuery. Many of these 
will update to the Candidate Rec documents when they exist. Also, many 
implementations support only a subset of XQuery, and the subsets vary.

Are you saying the tools you are using do not support the doc() function at 
all, or place restrictions on its use? Can you give me more information?

I've used Galax a lot and Saxon some and been happy with both. You can find 
links to them here:

Hope this helps,
