John agreed.

We can state that we are not precluding the use of business
rules - but its not our job to build those.  People in the ECLIPSE project
have already done much more there - so no need to re-invent those
wheels.

BTW - UML production rules can also create for example -
OASIS CAM templates, so we could list some expected interactions
that people may want to exploit here when using UML - but the key
thing is that we are not expecting that all aspects of a BPSS can be
constructed simply by using UML and production rules - but
implementers can certainly expect to be able to find a good degree of
compatibility nonetheless.

Thanks, DW.

This work item should be disposed of easily, the production rules were
required because UNCEFACT dictated a UML version of the BPSS content
(process model).  The architecture at that point required that the BPSS XML
be produced from the UML, hence "production rules".

With that architecture the well-formedness existed in the UML model.  By
removing the UML model we remove the requirement for production rules, but
also remove the well-formedness (semantic completeness) provided by the UML,
hence the need for well-formedness rules.

Point|From production rules to well-formedness rules;

mm1@
In the F2F in February, we discussed this briefly this work item:

Work Item 5-Production Rules
Describe boundaries for production rules in BPSS. Note: Starts to
provide boundaries between what is needed in a business collaboration
and what translates down to the engine.

Important points

    * It's original intent was to support UML to XML transformation.
    * Integrity checking is needed for the XML.
    * Production rules will be replaced with well-formedness rules.

Allocation:

    * v2.0: Document that production rules will be replaced with
      well-formedness rules. Gather requirements.
    * v3.0: Define well-formedness rules. Provide in technical
      specification and schema.

I would propose that we:

    * Define a summary statement in the v2.0 technical specification
      about production rules and their initial and future usage. These
      production rules or guidance have existed in ebXML BPSS since
      v1.01 (1.05, 1.1).
    * Close this work item for v2.0 only.
    * Work will continue in v3.0.

I would encourage your thoughts and we can bring up under Other Business
in tomorrow's meeting.

John (and JJ, Martin), I would encourage your feedback here as you may
have some ideas regarding the well-formedness rules that may apply. Thanks.
