Yes, that draws my attention, not (only) because I'm a Commons SCXML
developer, but because I believe this is the right way moving forward
for Shale dialogs (I'll articulate in detail in another thread). No
doubt that backwards compatibility should be maintained as far as
possible. To use Commons SCXML to also support the current dialog
notation, three approaches come quickly to mind:

1) Run a XML tranform under the hood (possibly tricky, since
dialog-configs can contain multiple dialogs).

2) Write a specific digester that can map dialog-config.xml to the
Commons SCXML model package [1].

3) Do a Java object mapping (basically walk the object graph) of the
Shale object model to a Commons SCXML one.

Any other ideas? Any preferences?
