I believe that: 1. it is not strictly true of the registered tag sgn-CH-de, except by the coincidence that "de" describes a language as well as a country; unless Switzerland has united with Germany when I wasn't paying attention. 2. there is no way that an RFC 3066 parser could have made such an assumption as there is no specification regarding interpretation of 2-letter subtags in the 3rd or subsequent positions. In particular, what you state as a rule appears nowhere in 1766 or 3066. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
