Sanda:
All you have to do is remove the xmlns:xml="..." attribute from the schema
tag - the import element should stay in place. I've tested this and it seems
to work on all of the XML editors and parsers I have on my machine.
See if this works in XMetal, and I think we won't have an issue.
Cheers,
Arofan

Arofan, and all.
Yes I have used XMetaL (same version, 4.6) with all of the previous DDI3
schemas - the published 3.0 as well as the various drafts that preceded
3.0.
I have never encountered this problem up until now.
I just tried to load the StudyUnit schema (3.1, review) and it worked
fine.
So that's all I can say so far.
Sanda.

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).
