I am at a loss to understand the rationale FOR it. The ABNF is conservative; it takes an active rule to allow something, but merely the passive absence of a rule to prohibit it. Why would you want to fill the ABNF with junk like "the same?" The purpose of quoting or otherwise bracketing particles in grammars has always been to characterise the quoted string as a single token to the parser something that would, by default, be treated as a series of multiple tokens, as would be the case here in a whitespace-delimeted syntax. Since the reason phrase is the last element of the first line of a reply, it can go on indefinitely until EOL without any additional syntactical information. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
