Perhaps it should say something like "Unless stated otherwise, a 
conforming implementation is required to implement all fields define in 
this specification."

I believe Required and Must are considered equivalent in RFC2119 and the 
main requirement for the spec is consistent usage.

Well, this is a style issue and personal preferences will of course 
vary. I personally like the way the Contacts API marks up the 2119 
keywords but I realize others may disagree. I think the main requirement 
is consistent use of the keywords and the secondary issue is markup.
