In your document, there are no dtd events to fire because there is no
internal subset, even if you setExpandEntities to false.  There is only the
external dtd and that is not handled by the declhandler.  The comment must
be coming out because the characters method got called during parsing of the
dtd.  I didn't expect that but it still leaves a valid internal subset.

I don't think there would be a way for SAXHandler to tell if the comment
characters came from the internal subset or the dtd.
