Tom, I agree that there should be a reusable typedef for language tags instead of copying a long pattern around. rfc6991-bis could be a home for this but work on rfc6991-bis stalled because we could not settle the debate about IP address types. Perhaps it is easier to roll an ietf-lang YANG module that initially just defined a language tag TC. <tp> Two additional thoughts. Martin Durst has seen the YANG for language tags in the I2NSF I-D and says that it is 'complete overkill'. Also, 10 IPR claims have been submitted against I2NSF I-D, albeit for older versions, with 'Possible Royalty/Fee' so I have gone off the idea of using anything from that WG. I see that others use just a length constraint for the basic format which is hardly worth a type.
