RE: Why Are Schemas Hard? (WAS RE: "Uh, what do I need this for" (was

1. What about Schemas is hard?
2. Are some of the issues about things Schemas cannot
represent (eg, the co-occurrence constraints)?
I'm missing something here. With a product like
XML Spy for sanity checking, I don't seem to find
the Schemas hard to develop. That doesn't say
that implementing a system around a schema isn't
hard, but I am curious what others are struggling with.
Yes, the spec is tough (they all are), but the primer isn't, there
are dozens of web articles on learning schemas, and
a week or so with a beta of an IDE seems to cover
the sanity checks.

We are in agreement there.
