Mike Beckerle commented on DAFFODIL-2490:
-----------------------------------------
Feature request withdrawn.
This feature is hard, and complex to implement within Daffodil.
It is easy to implement as a data pre/post processor on XML text or a SAX event
processor.
This is preferable than a change of this complexity to Daffodil requiring a
DFDL extension feature that is specialized to when the infoset is being
represented as XML.
> Feature to treat string of data as XML

> Key: DAFFODIL-2490
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2490
> Project: Daffodil
> Issue Type: New Feature
> Components: Back End, Front End
> Affects Versions: 3.0.0
> Reporter: Mike Beckerle
> Priority: Major
>
> More than once the need has arisen to convert binary data to XML where the
> binary data contains a string of data that is already XML. That XML is not
> escapified XML, it's regular XML.
> The surrounding binary data needs to be parsed and converted to XML, but the
> string of XML needs to simply be slammed into the XML text coming out of
> Daffodil.
> The inverse needs to happen on unparsing - the XML corresponding to the
> string has to be written out as a string (without escaping) and incorporated
> into the binary data.
> Note that such XML isn't necessarily adhering to DFDL's subset of XML schema.
> E.g., it may use attributes, etc.
> Nevertheless, the combined XML - the XML you get corresponding to the binary
> data part, along with the string of XML embedded in it, the resulting
> complete XML document does have an XSD and could be validated (if not by
> Daffodil, then by a separate validator)
