[DDI-SRG] schema for DDI 3.1

[A. Gregory]

Folks:

Here's what I don't understand. Presumably, XMetal didn't choke on the
existing, published 3.0 schemas which bind the xml namespace (see, for
example, the reusable schema module.) Why, then, now, does it suddenly
choke?

Sanda: did you use XMetal for the 3.0 version of DDI?

Cheers,

Arofan

One the one hand hand DDI should follow the spec. On the other hand DDI 
should validate in major editors and parsers like XMetal (Sanda 
mentioned it).

We should verify that DDI can be validated in major editors and parsers. 
When an issue raises just with one of them, we can take following action:
- document the issue on the DDI web site
- email the vendor about the issue (like I did with a previous version 
of XMLSpy).
