Going with the POSIX environment variable spirit, the user will have two
ways to use such variants:

   a) set LANG or LC_ALL to "de_DE collation=phonebook,currency=DDM"

   b) set LANG to "de_DE"
          LC_COLLATE to "de_DE collation=phonebook"
          LC_MONETARY to "de_DE currency=DDM".

The glibc-borrowed code already splits locale names at particular characters,
yielding a matrix of possible file names to look for. This code would need
to be extended to cover the new options semantics. It's in
  gettext-runtime/glocale/locale/loadfile.c
  gettext-runtime/intl/loadinfo.h
  gettext-runtime/intl/explodename.c
  gettext-runtime/intl/l10nflist.c
