Section 6.1.1 says:

   o  locale - optional, no default value: Specifies the language and
      country variant used for resolving spoken variables.  The language
      is defined as a two-letter code per ISO 639.  The country variant
      is also defined as a two-letter code per ISO 3166.  These codes
      are concatenated with a single underscore (%x5F) character.

It should say:

< to be specified >

Notes:

The RFC should better apply existing IETF standards and not
try to establish ad-hoc usage conventions and/or syntaxes
for details already well specified in the IETF.

In particular, it is considered an error (on top of page 26)
to not apply, and refer to, RFC 4646 (BCP 47) for the
definition of language tags.
RFC 4646 deliberately has modified and extended the earlier
conventions roughly corresponding to what is described here.
--VERIFIER NOTES--
Authors comment: BCP 47 wasn't out yet when the base spec was published.
A new protocol - hence a new RFC - should make the changes suggested here.
