As I pointed to rlb, there's a move on to replace dtd's with schemas;
schemas fix a lot of the nasty/ugly problems with dtd's & so it would be
nice not to lock into dtd's for the long run ...

rlb alos has serious concerns about memory usage:  he has something like
3000 transactions, which blow up gnucash to 50MB VSZ during xml file
write.  If going teh dom route causes similar memory usage ... that's
scary ...
