Subject: RE: [ubl] Minor Versioning Example (was [ubl] Minutesof Atlanti cUBL TC c all2 November 2005)


OK. Mike's example resolved my earlier concerns. 

Might I mention a new one. Eduardo and Arofan's paper
http://www.idealliance.org/papers/dx_xmle03/papers/03-04-03/03-04-03.pdf 
in section 4.1.3 mentions this. 
If the namespace is the same for minor versions could that
hinder customisations? A customisation has to be bound,
obviously, to a particular minor or major version and must
be immune from any affect of further minor versioning.

(This requires some assumptions about how customisation
might be done/recommended but the most obvious
mechanism is import/substitution groups while the Swedish
invoice customisation does demonstrate an alternative, I think.)

Of course it could be a rule that one only customises from
major versions. But what are the implications that a minor
version would introduce another schema model with the 
same namespace? Does this make it important to keep the
names of schema files from changing when importing for
a customisation?

This still doesn't change my agreement that we should use
redefine for minor versions, it's just something I think we
should think through (even in advance of the customisation
discussions).

All the best

Steve

The schemas validate at the NIST XML Schema and Instance Validation Web Services site (http://syseng.nist.gov/b2bTestbed/projects/xmlvalidation/schema_validation.html) which utilizes the  Xerces, Jing  and MSV parsers.


The instances also validate in Arbortext Epic Editor 5.1. Although this will not be a tool used by UBL implementers, I have found in the past that it is a good barometer of what is supported by mainstream XML applications.

I will try it out with other tools as soon as I can (which may not be for a while).
Hopefully some of our other members can give it a try...


> Does it force the use of the same namespace for minor versions?

Yes; that is why it can't be used by customizers.
