I suspect it's either carelessness, exhaustion -- there are only so many
three-letter acronyms, after all, and most of them are already in use by
some piece of software or other -- or, quite possibly, that the document
is in fact using the XML data model internally but has exported the file
in some compressed format, which may or may not be one of the various
"binary XML" representations that have bloomed and withered over the years.
I'm not going to look more closely; I seem to remember that the TTax
license had a "no reverse engineering" provision and I'm a firm believer
that the object of the game is to be as honest as the law allows.
