--------------------------------
Summary: Drop XML/XPath based data model in 2.0
Key: SCXML-250
URL: https://issues.apache.org/jira/browse/SCXML-250
Project: Commons SCXML
Issue Type: New Feature
Reporter: Woonsan Ko
The SCXML XML/XPath datamodel support has been dropped from the final W3C SCXML
1.0 specification [1], because of too many functional and semantic
complications and limitation, as well as lack of interest for implementing it.
The implementation of the XML/XPath datamodel in Commons SCXML has been
problematic for precisely the same reasons.
And not being able to provide such implementation properly by us (Commons
SCXML) actually has been one (final) argument for dropping it from the
specification...
In Commons SCXML 2.0, we need to drop the support for XML/XPath based
datamodel, and instead introduce a much easier to implement and support JSON
datamodel as alternative, for all current Commons SCXML support 'languages':
JEXL, Groovy and Javascript.
