Yeah. I've come a long way from my early enthusiasm for XSchema / DDML.
I think part of the vision that was somehow lost along the way was the
prospect of using XML tools to build, process, and store schemas. DDML
had high hopes for the (eternally-delayed) XLink, and was designed to be
simple enough to be processable that way.
At this point, I don't think schemas (such as they are) have proven
especially tractable this way. I'm moving in general to a notion of XML
as a canonical markup format, and think things like the non-XML format
for RELAX NG are a step forward at this point, not a step back.
