W3C releases working draft of State Chart XML (SCXML)

W3C releases working draft of State Chart XML (SCXML)

This working draft document describes State Chart XML (SCXML),  is a 
general-purpose event-based state machine language that can be used in 
many ways, including:

    * As a higher-level dialog language controlling VoiceXML 3.0's
      encapsulated speech modules (voice form, voice picklist, etc.)
    * As a voice application metalanguage, where in addition to VoiceXML
      3.0 functionality, it may also control database access and
      business logic modules.
    * As a multimodal control language in the MultiModal Interaction
      framework [W3C MMI]
      <http://www.w3.org/Voice/Group/2005/HST/SCXMLNotation.html#MMI>,
      combining VoiceXML 3.0 dialogs with dialogs in other modalities
      including keyboard and mouse, ink, vision, haptics, etc. It may
      also control combined modalities such as lipreading (combined
      speech recognition and vision) speech input with keyboard as
      fallback, and multiple keyboards for multi-user editing.
    * As the state machine framework for a future version of CCXML.
    * As an extended call center managment language, combining CCXML
      call control functionality with computer-telephony integration for
      call centers that integrate telephone calls with computer screen
      pops, as well as other types of message exchange such as chats,
      instant messaging, etc.
    * As a general process control language in other contexts not
      involving speech processing.
