Derived types and the TypeInfo interface

Hello,

Using DOM Level 3 Core, is it possible to find out if the type of an Element
or Attribute is derived from some specific type in the Schema?

What I would like to see is something like the Xerces
XSTypeDefinition.derivedFrom method in the TypeInfo interface.

Best regards,
Petteri Stenius
