Another rendering for this, which Marvin and I explored a little bit when writing our document, is:

I don't think we need two different tags. ActivityState only should work, as the substate concept is captured structurally. My personal preference is still for the subtyping approach, but I can't see myself winning on that one.
The nice thing about having two elements is that you can require the BaseState and StateName attributes, whereas one element would render them both optional. If re-use of StateName for the base states is desired, then we lose the ability to explicitly enumerate the names of the base states. But other than this use of XML, there is no conceptual difference, as far as I can tell. -- Chris
