I'm not sure about the SHOULD in the above. I'd only expect an RFC  
2119 keyword if we were recommending doing something specific that  
could help with interop. I don't think it makes sense to recommend  
(in an RFC 2119 sense) doing something without specifying exactly  
what since this is an inherently untestable assertion.
