Sometimes I think people are too young to remember when 
markup was a verb instead of a noun.  They would come 
to us with a set of documents and say, "Write a DTD 
for these." and we would ask, "Are these exhaustive 
examples?" and they would say, "What? Oh, don't worry, 
we can fix it if we find more." and we would and they did.

Not much has changed.

But the tag sprinkling process is a good model of why 
schemas can be treated as emergent controls.

Perhaps it depends on how readable a schema language it's using ;-) But
seriously, I don't think it's an either/or situation.  I want a spec to
have both prose and a schema.  If it doesn't have any prose, I'm going
to have to guess the semantics; if it doesn't have a schema, it's very
likely I'm going to have to guess some syntactic details.
