To get the base type, use getBaseType().
Simple types are always derived by restriction from the base type, so we
don't need a method for that. This is unlike complex types, where a
getDerivationMethod() is needed.
List and union types can be recognized from getVariety(). And if the base
type is anySimpleType, then they are constructed from <xsd:list ..> or
<xsd:union>. If the base type is not anySimpleType, then they are
restrictions of some other list/union types.

Please respond to
xerces-j-dev
OK - bug invalid.
In that case, how do you check for <xsd:restriction base="....">?
I suspect that I should be raising this on the user list - sorry for the
posts.
Cheers
