Type derivation in XSD comes in two flavors; extension and restriction.
Extension is easy to mimic even with DTDs. However how does RELAX NG
mimic restrictions (especially the nested ones) that involve facets like
xs:minInclusive, xs:maxInclusive?

Without the constraint that they have compatible content models then it
is just an xs:choice

Interesting. Could you point me at the part of the spec or tutorial that
discusses this functionality.
Thanks.
