isBuiltInType
public boolean isBuiltInType()
Determine whether this is a built-in type or a user-defined type- Specified by:

in interfaceSimpleType
- Returns:

This concept is used to support the notion of "pervasive" redefinition: if a component is redefined at several levels, the top level wins, but it is an error to have two versions of the component at the same redefinition level.- Specified by:

in interfaceSchemaComponent
