Sorry, my mistake. See below for correction. >That isn't supported by ABNF, and what I am proposing doesn't change that. In ABNF you can only >indicate character ranges using numeric representation.

So, my question then is whether I could use: mystringrule = %i(%x61-7A) Regards, Christer _______________________________________________ abnf-discuss mailing list abnf-discuss@ietf.org https://www.ietf.org/mailman/listinfo/abnf-discuss
