Thanks (and thanks to Rick's similar observation).  I hadn't realized 
that there was a lot of interop experience across different RELAX NG 
implementations on different platforms. That's good to know.

I also wish more specs would follow the RELAX NG pattern of being 
elegant, test-driven, focused on solving specific problems, etc.  The 
trouble is, there just aren't very many people capable of operating at 
the level that the RELAX NG inventors operate.  I've seen something 
similar to the XSD vs RELAX NG situation in the XML API space, 
participating in the DOM design by committee exercise as well as the 
XLinq design by world class designer 
(http://en.wikipedia.org/wiki/Anders_Hejlsberg)  exercise.  It's pretty 
humbling, and I don't think there's a formula for creating great 
technology without either a lot of evolutionary selection or a little 
bit of extraordinary talent. 

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.
