Other Efforts - Anything to Contribute?

In writing our Technical Note, I've been making sure that I take into
the work of various other groups. So far, I'm covering the following
groups:

OAGI Core Components (http://groups.yahoo.com/group/OAGI-CoreComponents)
UBL

If there is any work done by any other groups (such as UN/CEFACT ATG 2
and the CCSD Primer - which I've never seen), please forward them to the
listserv.

Thanks!
Joe
