Subject [jira] Commented: (SCXML-64) datamodel should not be allowed in transition.
Date Fri, 04 Jan 2008 18:59:34 GMT

    [ https://issues.apache.org/jira/browse/SCXML-64?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12556021#action_12556021

Rahul Akolkar commented on SCXML-64:
------------------------------------

Yes, as you point out in the comment in code, the plan has been to have a validating digester,
but the W3C hasn't provided a useable DTD/schema yet. I do contend that the act of validating
SCXML documents is better placed with XML editors / code generators / other authoring tools
etc.

 Acording to the SCXML spec datamodel is not allowed in a transition only globally and at
the state level.
