Several years ago, I had a draft on track for experimental RFC returned, and one of the comments was that it was using RFC 2119 language (MUST/SHOULD/MAY) when, as an experimental RFC it shouldn't. I've now been told that recently experimental RFCs are being approved with such language. I've been encouraging my WGs to not use such language, in an effort to avoid having drafts returned, but perhaps I'm mistaken. Could you clarify what the policy is w.r.t. RFC 2119 language in experimental drafts? jak
