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.

Yes, even a typedef like this

  typedef language-tag {
    type string;
    description "A language tag according to RFC 5646 (BCP 47).
  }

would do. Note that RFC 5131 defines a LangTag TC for the SMIv2 world.
Petterns are nice to have to detect wrong values "early" but once
patterns become very complex, the likelihood increases that they are
wrong.
