Attribute Entities not affected by XMLInputFactory.IS_REPLACING_ENTITY_REFERENCES or XMLInputFactory.SUPPORT_DTD

I'm sure there is a good reason for this, but I couldn't find any documentation telling me why.

I currently want to process an XML document and leave it exactly as it comes in. I.E. no resolving of entities.
XMLInputFactory.IS_REPLACING_ENTITY_REFERENCES or XMLInputFactory.SUPPORT_DTD will do this for entities within elements, but there seems to be no way of leaving entities in attributes unresolved.

I tried using SUPPORT_DTD == false, and then using a custom "com.ctc.wstx.undeclaredEntityResolver" that just returns the entity as is:

public class UndeclaredEntityResolver implements javax.xml.stream.XMLResolver {

	@Override
	public Object resolveEntity(String publicID, String systemID, String baseURI, String namespace)
			throws XMLStreamException {

		String entity = "&" + namespace + ";";
		return new ByteArrayInputStream(entity.getBytes());
	}
}

but this will just result in a recursive entity problem.

Am I missing something?
Is there any nice way I fan accomplish this?
