According to the W3C SCXML specification,<ref>[http://www.w3.org/TR/scxml/ State Chart XML (SCXML): State Machine Notation for Control Abstraction specification]</ref> SCXML is a general-purpose event-based state machine language that can be used in many ways, including:

The draft W3C [[VoiceXML]] 3.0 specification<ref>[http://www.w3.org/TR/voicexml30/ Voice Extensible Markup Language (VoiceXML) 3.0 specification]</ref> includes State Chart and SCXML Representation to define functionality.

The W3C document Authoring Applications for the Multimodal Architecture<ref>[http://www.w3.org/TR/mmi-auth/ Authoring Applications for the Multimodal Architecture]</ref> describes a multimodal system that implements the W3C Multimodal Architecture and gives an example of a simple multimodal application authored using various W3C markup languages, including SCXML, CCXML, VoiceXML 2.1 and HTML.
