That';s what I saying above that xml seems to be the hog in terms of
it's user defined tags. Is that somewhat a confirmation of my hunch,
that it's the length of the users predefined tags that add to the
above mess, and that maybe a lessened tag system in accordance with
xml might be better, or a simple <a> tag <b> tag in the xml(other
files) with an index  to point to a and b would be better.
