Nice work. Yes, that seems to be the problem. I was able to track it
down to some changes in the DTD. As you know, we (Debian) patch(ed) the
DTD to fix some bugs, which were also fixed in the official DB XML 4.4
release. That's probably the reason, why you see the error too and why
onsgmls does not complain. When I replace the patched version with the
original one, the error disappears. Attached are the important
differences, that were also applied to DTD in 4.4. So these changes seem
to be the reason for the error.
