An alternative, for the core document, is merely to note that display of 
identity-related fields is a highly sensitive aspect of application 
usability and that consideration of the design issues affecting it are 
outside the scope of this specification.

Having the core document give ANY normative guidance on user interface 
design and cognitive processing concerns -- note the draft text says 
"should" -- or for that matter any guidance at all is not going to help the 
focus or utility of the document's main purpose.
