RE: [xtm-wg] Promotion of Conceptual Model

["Graham Moore" <gdm@empolis.co.uk>]

I think it is critical that the model be in the main part of the spec. This,
as steve said, is the isness, the essence of what XTM is. It anambiguously
conveys what the syntax represents.

Subject: [xtm-wg] Promotion of Conceptual Model


I personally would prefer that the Conceptual Model be part and parcel
of the main part of the Spec, along with the DTD.  I just don't want
to call it an "Annex".  I'd rather treat it as a "clause" (to put it
in ISO terms, and since we're evidently already using the ISO jargon
term, "Annex").

The draft Dallas minutes advise that we make the conceptual model an
Annex.  The thinking behind this decision was that we needed to be
able to publish the Spec regardless of whether the Conceptual Model
became available for publication.  I think we should reconsider this
policy, and, instead, move the Conceptual Model forward, not treating
it as an Annex, thus avoiding any possibility that implementers might
miss the Conceptual Model simply because it only appears in an Annex.
More to the point, the Conceptual Model is of the very essence of what
we're talking about in this Spec; it's no less essential to software
developers than the DTD is.  The Conceptual Model offers a vital
perspective on the nature of the information that the DTD is designed
to convey in interchangeable form.

In any event, we already have the annotated UML diagrams, and, if need
be, the diagrams are self-sufficient.
