That's not completely true.  The GnuCash XML backend is hand-coded, and
historically it will complain if it sees an element that it does not
know about.  So no, it is not validated, but it is rather rigid in its
reading (at least historically).  Feel free to try it.  :)

It might not error out, per se, but it will cause load failures.

I agree, but we want to make the change so that you can still use 2.6
w/o using the new feature and still load the data file into 2.4.
