State Chart XML (SCXML) is currently a
Working Draft published by the World Wide Web Consortium (W3C).
SCXML provides a generic state-machine based execution environment based on Harel
State Tables. SCXML is a candidate for the control language within
multiple markup languages coming out of the W3C (see Working Draft for details).
Commons SCXML is an implementation aimed at creating
and maintaining a Java SCXML engine capable of executing a state machine defined
using a SCXML document, while abstracting out the environment interfaces.
