Re: [ubl-dev] Code list extensibility and substitution groups

["David Webber \(XML\)" <david@drrw.info>]

Duane,

If only it were that simple - schema implementation nuances
are subject to communities of interpretation.  One man
argues for a behaviour - the other the opposite.

It is what it is - and the issue is that schema use cases
do not include these B2B integration ones - so you are
using this stuff out-of-band.

That was the primary design impetus behind CAM in
the first place - the realization that we are just solving
a different set of needs and customers.
