Andrew,
If you are using xerces, there is this "feature" available (note it is
not a "property"):
http://apache.org/xml/features/nonvalidating/load-external-dtd
This feature is referenced here:
http://xml.apache.org/xerces-j/features.html
I believe you would call the setFeature() method on the SAXParser once
you created it. If you are using j2sdk rather than xerces, I don't know
what the equivalent feature, if any, would be. But I haven't tried
looking for it.
I am using xerces, but I haven't tried setting this feature yet. If it
works, I will let the list know and provide a code sample.
JAXB team, it might make things easier to provide a way to set both
features and properties for the underlying SAX parser through the
JAXBContext and/or Marshaller and Unmarshaller interfaces. But on the
other hand, providing this might make things easier for the XML impaired
to mess things up by not forcing them to learn the dense XML apis.
