The name in a static template reference should be the name of another template so in your example you'd have to write (templateRef name="Template_2"/). If we assume you do that, Template_1 will include two fields with the same name MDEntrySize. Even if it's not prohibited by the specification, it doesn't make much sense in a real application. Depending on your implementation the second occurrence would probably overwrite the first (if it works at all). In any case, the correct behavior for the two fields would be to have two different pmap bits but they would share the same entry in the global dictionary (since they have the same name). /David > Hi all, > > I want clarification regarding Template Reference Instruction.
