When I read SCXML specification first (previous draft), it was clear for me.
But when I began to implement SCXML interpreter, I had so many questions that  any progress was not possible.

What was really helpful for me is classic Harel's article "STATECHARTS: A visual formalism for complex systems".

I would like to see Harel's semantics in the final document.
It's simple, clean and useful for end users.
And it introduces harmonious paradigm which help to understand SCXML program to think in terms of it and to develop complex programs.

It can be present conjointly with the algorithms.
But algorithms must conform to the semantics definitions, accurate them and illustrate them.

Now I have full implementation of the current draft but don't have power to check conformity to the algorithms. Almost because difference in methods of implementations.
