RNG can specify constraints on simple types, but not nested constraints.
How does one restrict complex types in WXS?

Agreed.

In the spec:
 http://www.oasis-open.org/committees/relax-ng/spec-20011203.html#IDAG3YR

Section 4.7, 3rd paragraph.

In the tutorial:

http://www.oasis-open.org/committees/relax-ng/tutorial-20011203.html#IDA3PZR

Section 13

Note that there are no constraints on the redefinition: the new rule need
have no relation to the old.
