The usage above, although much earlier, reflects the Protocol Specification/ Applicability Statement split rather well. But 2119's language makes the two terms substitutable for and equivalent to each other, which is about as close a definition of "synonyms" as one can find. What I said is that making them equivalent was probably a mistake and that treating them that was should be discouraged. Others expressed agreement with that assessment. Personally, I don't think the problem is severe enough to reopen 2119. If others disagree and believe that 2119 is generating enough problems to be worth an update, I await a draft. So, other than quibbling about the "synonym" issue -- not generally, which no one has claimed, but in context with 2119-- are you disagreeing and, if so, about what? john
