I agree. At http://www.w3.org/Bugs/Public/show_bug.cgi?id=3000#c10 Yves said,
he wants "out of the box" schemas for ITS. The example I created at
http://www.w3.org/Bugs/Public/show_bug.cgi?id=3000#c11 is such an out of the
box schema, with all disadvantages Sebastian mentioned: no predicatbility and
cost of loose schemas.
You can't have both a loose schema and schema which is good for validation. I
would go for the later, hence: change nothing and just tell people that they
can use namespace for extensions (what we already do).
