I think the difference between down-played error and regular error is  
not very meaningful. The actual material difference between different  
diagnostic classes is not friendliness in the validator, but rather  
whether authors can still use the feature if they have a requirement  
(self-imposed or otherwise) to produce fully conforming content.

Thus, I think a suggested non-error diagnostic would be better than a  
requirement for a down-played error, in that it would give the  
advanced experts who choose to disregard the warning the opportunity  
to have their content be conforming.
