.xsdconfig qname element should allow specifying only element or only complexType

Currently the <qname> element in .xsdconfig files allows only the name and javaname attributes to be specified.

If you have a schema with a global type and a global element with the same name and you try to map that name to a non-default javaname using the <qname> element in a .xsdconfig file then you will get that one of them maps to the javaname and one of them maps to javaname + "2" in order to avoid collisions.

Suggest that we update <qname> to allow a third attribute which specifies whether this mapping applies to elements only, types only, or both with default being both.
