Timing and the zeitgeist.  What ever gets in front of the most people
with the least expertise with the most clout first wins.  One wishes it
were otherwise, but that it the nature of being in a business that has a
high requirement for deep technical expertise AND a very broad audience.
Branding as an approach to marketing relies on this.

So did HTML.  It works for everyone because it is simple.  OTOH, to do
most jobs, it isn't nearly enough so the actual workspace manifold is
quite complex.

Scope and reach:  there is an inverse relationship of subject views to
objective implementations.  The more operations an object/class
subsumes, the fewer the users.  The more users, the weaker the semantic.

That is the definition of a situation semantic.  One hopes for a
feedback between the environment and each subjective view similar to an
infinite impulse response filter so that the plot for the curve is
responsive but smooth.  If input processing halts, slows, or has bogus
or repetitive values, the output will stall or cycle around a
coordinate.

Market share has the effect of hystereis.  XSDs in their complex
applications aren't a cheap means even if it seems they should be.  XSD
tends to follow DTD development characteristics:  they become very
complex.  See scope and reach.

And then there's the problem that great technology won't necessarily
succeed against OK technology unless a lot of forces align to make it
happen.  Hopefully RELAX NG can flourish in some niche in the short run
and influence some next generation schema language in the long run, even
if the forces don't align to make it a mainstream success.
