People seem to be flocking to Perl+XML and Java+XML quite rapidly, XSL
aside. The biggest cost of Omnimark was not the purchase price
(although $12K or more per seat [per annum, I think] would give most
programmers reason to pause), but the cost of maintenance.
A lot of people know Perl and Java but almost no one knows Omnimark,
and maintaining a system that relies heavily on scripts written in an
esoteric and virtually-unknown language can be extremely difficult and
painfully expensive, when it's possible at all.

Gotta be pragmatic here -- the editing software can declare that
attributes contain text, period, end of discussion. On import, the
editor can simply expand the entities and then forget about their
boundaries. I think that most users can live with that.

The problem is simply one of matching up skills -- it's hard to find
people who can write transformations (in any language), and it's hard
to find people who can write DTDs; it is painfully difficult to find
people who can do both.
All the best,
