The isDerivedFrom method checks if this TypeInfo derives from the specified ancestor type.
Get schemaTypeInfo on an element of type Union that belongs to a document with an XML schema.
Invoke method isDerivedFrom with derivation method union and verify that the value returned is true.
Verify that emType is derived from emp0004_5Type by union.
