Hi Marc,

This really isn't a conversation about the p3p schema so I've changed the 
subject line.

So lets assume it is.

No more than you did.

No.  You are calling things you don't like errors, with no justification 
for so classifying them.  What rule have they broken?

I believe I have demonstrated that I can extend your schema and introduce 
'incorrect' values in a similar manner to the way you did for the original 
schema.  Thus your preferred semantics for range does not offer the 
advantage you claim.

We have about done this to death I think.  Unless you've got a new killer 
argument, or a lynch mob, I think we'll just have to disagree.
