[dfdl-wg] More documents

[Steve Hanson]

I'll see what I can come up with.

As far as the embedded XML goes, I put it there as we will be asked this
question. Thinking it through, maybe we should simply treat it as a BLOB
and leave it to the user to take and parse using an XML parser as an
independent operation. This is symmetric with an XML document containing a
non-XML BLOB as CDATA that needed to be parsed using DFDL.

Thease are great examples.  Can someone give me fully documented
data files from which to try to construct such examples?

By the way, I'm not sure whether embedded XML is within the scope
of DFDL--it gets insanely hairy.

But the others are exactly the kinds of things that the core standard
must either cover or have an extension mechanism that covers.
