.SH "Detailed Description"
.PP 
This set of classes is a basic implementation of State Chart XML\&. It is not complete, nor is it necessary conformant to those parts it implements\&.
.PP
Currently Coin uses SCXML for managing 3D viewer user interaction (the non-model-interaction part) - the examiner navigation mode in layman terms\&.
.PP
The Draft Specification for SCXML is at http://www.w3.org/TR/scxml/\&.

State Chart XML
The \fBScXML\fP part of Coin is a basic, non-conformant, partial implementation of State Chart XML, based on the W3C Working Draft 16 May 2008 of SCXML http://www.w3.org/TR/2008/WD-scxml-20080516/\&. The latest version should be at http://www.w3.org/TR/scxml/\&. Read that document for a basic understanding how SCXML documents should be constructed\&.
.PP
Coin uses SCXML for setting up its navigation systems, to be able to remove hardcoded logic for user navigation and externalize it into XML files\&. This makes it easy for users to customize the navigation system for their own purposes\&.
.PP
Unsupported Items:
.PP
.IP "\(bu" 2
The <parallel> element is not supported as intended with parallel states\&. Coin will just treat it as an ordinary <state> element for now\&. Parallel states is not high up on the priority list, so expect this to be handled after a lot of other functionality is in place\&.
.IP "\(bu" 2
The <datamodel>-related part of the specification is not fully supported\&.
.IP "\(bu" 2
The 'target' attribute in the <transition> element can only identify a single state currently, not multiple as you would have to when having support for <parallel> elements (which we don't have)\&.
.IP "\(bu" 2
The virtual state elements like <history> and <anchor> are just implemented as dummy states for now and do not do anything in relation to what they should actually do\&.
.PP
.PP
For learning more about how \fBScXML\fP is implemented and used in Coin, take a look at $COINDIR/scxml/navigation/examiner\&.xml (or in the Coin source directory, data/scxml/navigation/examiner\&.xml) for an example of how an SCXML system for camera navigation looks, and look at the source files in src/navigation/ for the C++ counterparts to the same SCXML navigation system\&.
