'''SCXML''' stands for State Chart XML: State Machine Notation for Control Abstraction. It is an [[XML]]-based [[markup language]] that provides a generic [[state-machine]]-based execution environment based on [[Harel statechart]]s.

SCXML is able to describe complex [[finite -state machine]]s. For example, it is possible to describe notations such as sub-states, parallel states, synchronization, or concurrency, in SCXML.

==Goals==

Line 43 ⟶ 44:

*As a high-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, 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 management 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.
