Hi, Two comments:
1. Maybe I'm confused but it seems to me that the RESPONSE-CODE field of 12 bits plus the INFO-CODE field of 16 bits is 28 bits. So I don't understand the 2nd paragraph of Section 3.3 that talks about their concatenation fitting within 24 bits. 2. On the code point space for INFO-CODE values, the maximum possible in 16 bits is 65535, not 65536. I also don't understand the relatively small number space set aside for "first-come first-served". That policy only make sense to me when then is a large range of values available. If there is going to be a first-come first-served interval, I'd suggest that below. But I'd be just as happy to get rid of it and only have specification required and experimental/private. Generally speaking, error codes are things you want to understand so a minimum of specification required makes sense o 0 - 32767: Specification required. o 32768 - 65279: First come, first served. o 65280 - 65535: Experimental / Private use Thanks, Donald =============================== Donald E.
