I'm under the impression that this will be a standard Unicode mechanism,
defined in principle by TUS and in detail by the upcoming revision of
UTR #51, with data (but no additional rules) supplied by CLDR.

Like Philippe, I don't believe the hyphen is "redundant." ISO 3166-2
requires it (Section 5.2), and the syntax diagram at the end of
L2/15-145R shows it:

B ((TL{2} (TH (TL|TD){3})?) | (TD{3}))
