---------------------------
Resolution: Fixed
Fix Version/s: 2.0
> 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
> Fix For: 2.0
>
>
> 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.
