I did have some free time this evening so I gave it a whirl.  I did a cvs
update just to make sure I was current, compiled with the debug module
enabled and recompiled my test source including the above snippet.
Setting the LD_LIBRARY_PATH to the appropriate location and cranking up
gdb I spent around 15 minutes or so stepping through the library internals
after initially hitting the xmlDocDump breakpoint.  The only time I saw
reference to DTD was a series of if(blah==FOO_DTD) (greps source
looking.....) which appears to be from xmlNodeDump() in tree.c if(cur-type
== XML_DTD_NODE) but using gdb's stepi xmlDtdDump was never called.

(digs a bit more setting breakpoint at xmlAddchild())

xmlAddChild() as written above is being called.

If I can provide any further information let me know..I'll debug until the
cows come home to get this worked out =) (Keeping in my mind that I could
just as easily scrap the dtd idea..but I'm wanting it there for
completeness)
