RE: XML Schema for XTM DTD

This looks like a reasonable project for the next edition of XTM.

Subject: Re: [topicmapmail] XML Schema for XTM DTD



(Max and Daniel: please join TOPICMAPMAIL, and stop using the OASIS
list. That list really shouldn't be used any more.)

This is an attempt to summarize the thread, which has really gone all
over the place, as threads tend to do.

It seems that there is a significant number of people who want an XSDL
schema for XTM. Some want it for political reasons, others because
their tools require it.  To me that's reason enough, and it means that
the next XTM syntax specification should include an informative XSDL
schema.

Since this will be published by ISO SC34, which also creates RELAX-NG,
I think we should add an informative RELAX-NG schema as well, for
political reasons. The extra work required is slight, and I've always
wanted to learn RELAX-NG anyway. :)

As far as I can see, both schemas should constrain the XTM syntax as
it will be as tightly as possible, but do nothing beyond that. The
syntax itself should remain the same, and the DTD should continue
being the normative specification of the syntax, together with the
prose. 

Comments? Opinions?

If nobody complains too much I'll just add this to the next XTM syntax
draft. I can start from Max's proposal for the XSDL one, and can do
the first RELAX-NG proposal myself. Then people can comment on those.
Then the proper ISO process can roll on, and if the committee does not
accept the appendices, out they go.
