Ate Douma resolved SCXML-276.
-----------------------------
Resolution: Fixed
> Simplify and generalize reading and writing SCXML content and data element
> body values
> --------------------------------------------------------------------------------------
>
> Key: SCXML-276
> URL: https://issues.apache.org/jira/browse/SCXML-276
> Project: Commons SCXML
> Issue Type: Improvement
> Reporter: Ate Douma
> Assignee: Ate Douma
> Fix For: 2.0
>
>
> The SCXML specification allows for various ways to define and provide content
> and data element 'values', either embedded as XML element children or as an
> external resource.
> Such a body value can be parsed as:
> * Java object(s) mapped from (detected) json string
> * XML Node (single child element)
> * XML List<Node> (multiple children)
> * plain text (no child elements)
> For the <invoke><content> element Commons SCXML *only* supports the (most
> common) embedding of another SCXML document.
> And as the SCXMLReader uses StaX, not XML DOM for parsing, such an embedded
> SCXML document (currently) needs to parsed as XML text.
> Therefore a 5th value type will be used:
> * XML text (single XML Node serialized to text)
> When writing a SCXML document back to XML, the parsed values may need to be
> converted back to text (Json string) or XML Node (XML text) first.
> When writing the json string or plain text, if one or more of the original
> (read) XML element children was encoded in a CDATA section, the (coalesced)
> text will be encoded in a (single) CDATA section.
