I suspect the latter. If true, it might be worth mentioning that, or somewhere early in the draft mention that this spec is for vCard 4.0 only. > I'd love to hear from the WG here, but given vCard 5.0 can at least in > theory be completely different, I think the correct thing to do would be > to restrict this jCard document to 4.x and when 5.x comes around create > a revision of the document.

For example, I recently read a suggestion for signed vCards > that might use a version "4.0s". I'd prefer "valid until revised by another document", which is equivalent to not saying anything since that's how RFCs work. Therefore, my suggestion would be to simply remove this sentence: "Similarly, the value of the version property MUST be "4.0"." Simon
