[jdom-interest] Embedded DTD

[Stratton, Jason]

Hi all,
I have an XML string that I use JDOM to parse with Xerces' SAX parser.
Without doing anything else to it, I generate an XML string from the JDOM
document.

The original XML string had an embedded DTD. The output XML string is
stripped of the embedded DTD and all of the XML element values.

If I remove the embedded DTD, the generated XML string has all of the
element values, as expected.

The design decision to use the embedded DTD was not mine and it is possible
that I can convince the powers to use an external DTD, but I would like to
understand what is going on.

Is this a Xerces thing or a JDOM thing? Is it a bug? Any ideas on how I
should proceed?

Thank you.
