Mostly in the way output is being done. I'm using a JDOM document for
my stuff, which I append to as needed. Cayenne uses a PrintWriter,
which it writes to when needed. I guess it's a matter of taste, but I
like JDOM taking care of things for me. Likewise, JDOM has rich
support for formatting the output, which goes above and beyond the
"indent" string :-)
Additionally, Cayenne outputs <property> tags, which is good and all,
but is not really compatible with output from stuff I'm doing. Maybe
this isn't really necessary though.

Hmm . . . would it be best then to modify the auto-generated code to a)
implement XMLSerializable, and b) provide a default implementation of
encodeAsXML()? I just think it'd be great to be able to encode a
dataobject "out of the box".

No, that's the confusing part. That's just using
java.beans.XMLEncoder. I'll trace through the code again just to be
sure, but it's fairly simple.

Do you know whenabouts this took place so I can look at the mailing
list archive?
Thanks again,
