Database extensions for MS Access?

I need to create an end-to-end XML demo featuring data being extracted from a database, converted into a sectoral standard XML vocabulary and then updating another database with its own dialect for the same data.  Preferably on a stand-alone Windows 2000 laptop.  I'm OK with XML Schema and XSLT and I could knock up a couple of Access databases. Then I'm hoping o:XML could generate XML from the first and update the second.

Could out-of-the-box MS Access and ObjectBox talk to each other?  Could o:XML read and write to that all time classic of databases, The Northwinds?  What might the <db:connection/> look like for that?

(Sorry for lowering the tone and using the M$ word ;-)
