   1. Name of requester: John Cowan
   2. E-mail address of requester: cowan at
   3. Record Requested:

      Type: variant
      Subtag: qxaaa..qx999999
      Description: Private use

   4. Intended meaning of the subtag:

        All variant subtags beginning with the letters 'qx', with from 3
        to 5 following letters or digits, are reserved for private use.
        This is parallel to the existing reservations for language,
        script, and region subtags, and serves the same purposes.

   5. Reference to published description
      of the language (book or article):  None
   6. Any other relevant information:

        The use of "-x-variant" is semantically equivalent to a
        private variant subtag, but in a system where singletons (or
        'x' specifically) are syntactically disallowed, private variant
        subtags allow the creation of tags with identical syntax to those
        using registered variant subtags.  2,238,974,784 subtags should
        suffice for all purposes.

The peculiar excellence of comedy is its excellent fooling, and Aristophanes's
claim to immortality is based upon one title only: he was a master maker
of comedy, he could fool excellently.  Here Gilbert stands side by side
with him.  He, too, could write the most admirable nonsense.  There has
never been better fooling than his, and a comparison with him carries
nothing derogatory to the great Athenian. --Edith Hamilton, The Greek Way
