Got a quick response from Tim. While he expresses his regret for not
being able to join us at the call this Thursday (tomorrow), she sent
the following: (01)

From: Tim McGrath
To: yimpp@xxxxxxxxxxx
Subject: UBL models (02)
Peter, definitely the 're-usable' is the one to use. the other is
more conceptual. The 'normalised' model is more like a relational data
model in that it is has things like many-to-many associations, etc.
We created the other models from this by navigating specific paths
based on our document requirements. So the other models are what we
use for creating schemas.
// (03)
I'm sure we'll probably want to learn more about the differences (as
we are, in fact, trying to re-construct, or at least, get an
understanding, of UBL's conceptual model here (and not building
applications, per se). However, the prompt that we should start from
the "re-usable" spreadsheet is most helpful. (04)
