[xml bibliography]

I'm trying to use word 2007 to write a scientific document, so I started
using the new tools to insert citations and bibliography. All this is nice,
BUT I can't import my bibliography database to word, this is what Im doing:

Access:
Assign the same labels to these use in word (Author, tag, etc.)
Export data to a *.xml file
Word Manage Sources:
Browse,
Choose my file

Error: this is not a bibliography file
It is highly inefficient to write each citation using the tool design for
that in Word, especially when one is using about 300 citations
I have been looking for the file:
http://schemas.open.org/officeDocume...6/bibliography

Which seems to have the attributes for a bibliography file, but yet no success
I'll appreciate any help
