SCXML

• Couldn't you have created a conventional wiki page? - Oh, we have a HomePage too, just for you.

• Will Commons SCXML engine be able to execute this state machine? - You'll have to try that, but as a project we sure hope to.

• I've got a question, can you answer it? - Take a look at the FrequentlyAskedQuestions.
