I guess I am not familiar enough with xpath to conceive of a case when
the DTD would change the xpath result. Any demonstration of this would
be appreciated. :-)

Unfortunately the files processed are from various external sources, and
are not under our control.

Perhaps what we need is a flag to prevent the DTD from being used, or to
prevent attempts to fetch it from the network?

Thanks for your help in figuring this out.
