I don't agree here. I think they MUST use the new format. That way you 
can build a user agent that doesn't need to understand the 1.0 format. 
Of course this is in an extension and they must ALSO use the 1.0 
format.

According to what we discussed the 1.0 schema will be via a dynamic 
transform referenced by the policy with the address created by the 
xslt transform (with schema writers free to provide their own if they 
wish)

But then you need to require it - see point 1.
