Personally, I'd rather see a recommendation that everything use the same separator whenever possible, rather than recommending that everything use some separator that isn't ambiguous. Otherwise, you run into lots of conversion problems when you try to pass strings between different protocols/apps/ management tools/etc. Sometimes that's unavoidable, but the point of a recommendation is to avoid problems whenever you can. -Dave > Seiichi Kawamura > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.6 (MingW32) > > iD8DBQFKDL/EcrhTYfxyMkIRAhyxAJ47YJ4w9QHjvaRY2TCiUBRvBFaXJgCeNQF1 > lFyVqX2q62QkCwDVTmefEBs= > =7ZvM > -----END PGP SIGNATURE----- > -------------------------------------------------------------------- > IETF IPv6 working group mailing list > ipv6@ietf.org > Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 > -------------------------------------------------------------------- -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
