Hi All,
Under what circumstances should a type redefinition create an error
condition regarding multiple definitions of the same type?  In
particular, if a type is redefined when there is also an include that
indirectly loads the type definition, is this an error condition?
For example:
    Company.xsd redefines the Address type from Location.xsd which
includes Address.xsd
    Company.xsd also includes Employee.xsd which includes Address.xsd
Should I receive errors about duplicate definitions for the Address
type?  If this is not valid, how do I properly redefine the Address type
within the Company.xsd schema?
Regards,
    James
