I assume it would help, but I was testing similar code within Intake and
did have the root element set correctly. Basically what happened when I
added the xml declaration and doctype was that xerces finally parsed my
dtd. I know it did this because I had errors in the DTD that led to
exceptions. Once I had the dtd correct, I get no further
exceptions/errors from xerces, regardless of whether the xml file was
valid.

I would like to get it figured out directly with xerces. Torque's
XmlToAppData class contains the line I have commented out below. I
added the the second feature. My understanding is as follows: the first
feature sets validation to be optional depending on whether xerces was
able to find the dtd. The second feature tells xerces to validate. So
with the first line commented out xerces would throw an exception if it
could not find the dtd. The first line without the second would not
tell xerces to validate. But obviously my interpretation is not
completely correct, as I am not getting validation under any
combination.
//parser.setFeature(
// "http://apache.org/xml/features/validation/dynamic",
true);
parser.setFeature("http://xml.org/sax/features/validation",
true);

I assume the fact that the root element is wrong has not been caught
because no validation is occuring. Torque does not really care about
the root tag, it is just there to make the xml correct.
