It can be any name, it doesn't need to start with ModuleTag_ . So you can just name your tags after the module that uses them (much easier!). Like
Code:
Behavior = BaseRegenerateBehavior BaseRegenerateBehavior_1
End
The only time you ever need to refer back to the name is when you use the ReplaceModule directive to replace one module with another. But AFAIK that is only for map.ini files.
