Agreed. But then there's CP 11.1: "Use W3C technologies when they are 
available and appropriate for a task and use the latest versions when 
supported." This limits the scope a bit.

Yes, but you can't expect user agents to support your own custom DTD.
And you can't use custom HTML DTD's with a W3C HTML PFI:

bit more work than just validation.
