tags inheritance

[tschoepping]

My idea/request is quite straight forward. When I use tags, I frequently end up using these similar to classes in OOP, but I am missing inheritance.

For instance, if I was to model cars I would like to do something like "A Mazda 3 is a Mazda is a car." In this example I would like to define two tags: "Mazda" and "car" so when defining the "Mazda 3" element I can simply use the "Mazda" tag and that in turn will implicitly make "Mazda 3" a "car". Currently I have to set both tags for each element in my model, which is annoying, quite verbose and a potential source of error.

Without any knowledge about the implications of such a change, this sounds like low hanging fruit to me.
