Maybe I have a biased perspective because I only hear about the
problems and not the great mass of conforming schemas! Anyway, we're
planning to present our experience and evidence at the Schema
Experience conference so that people can judge for themselves.

I generally agree, except that more and more tools are forced to add
"buggy tool compatibility modes" to make this happen with minimal
customer pain. Those reduce the presssure to actually conform, and
create de facto profiles that we'll collectively be stuck supporting
for years to come.
