<action dev="rahul" type="update" issue="SCXML-6" due-to="Tim O'Brien">
[02-05-2006] The Commons SCXML object model is now decoupled from
the SCXML execution engine instance. The Commons SCXML object model
is now stateless. For example (incomplete list):
<ol>
<li>A "SCXML" object no longer contains a root "Context"</li>
<li>A "State" no longer contains a "Context"</li>
<li>A "Transition" no longer contains a list of "SCXMLListeners"
attached</li>
<li>A "History" no longer contains the last known configuration.
</li>
</ol>
The advantage of this decoupling is that the SCXML document can be
parsed once and reused across multiple execution instances,
concurrently or otherwise.
