This is great!
It is along the lines, which I was thinking of and it proves that we need
not re-invent the wheel.

p.s.
(1) There are/will be available
- language symbols (for spoken or written language - problem: how to cope
with script variants or change of the writing system? -->script code [can
all cases be covered?])
- country symbols (to 'qualify' language variants - problem: how detailed
can/shall dialects be covered? -->sub-national entities [can all cases be
covered?])
- script code (to 'qualify' differences of writing system for same language)
- sign language symbol (--> sgn - question: are there more problems IN
REALITY, if "sgn" is combined with language symbols or if "sgn" is combined
with country/region symbols?)

In this connection it is important to decide IN PRACTICE whether to put
"sgn" into the list of language symbols or into the list of script symbols
or ???
(2) ISO 639-1/RA - assisted by the JAC - has to find out, whether an alpha-2
symbol for sign language is needed or not.

The Library of Congress considered the introduction of a code for sign
languages into the MARC Code List for Languages several years ago. This
is the language code list upon which ISO 639-2 is based. We worked
closely with experts from Galludet University in determining which types
of sign languages to represent with separate codes. In the end, the
decision was to define one code (sgn) for sign languages, because defining
separate ones for different country's signed languages would result in
hundreds of additional language codes. Because the purpose of this
language code list is for bibliographic control, and it is often used in
electronic catalog records using standard cataloging rules, the Library of
Congress provided a document with guidelines for indicating sign
languages:
http://lcweb.loc.gov/marc/signlang.html

The above document refers to specific fields in the MARC record used to
include language information about a resource. Although these may not be
useful for those not using MARC, the point is that the particular type of
sign language may be indicated in the record in addition to using the sgn
code.

Note that in the MARC Code List for Languages, references are included. We
have included references from particular types of sign languages to the
general sign language code . So far we have only included those for which
we have received material, but the list of individual sign languages for
which sgn is used as a collective code could certainly grow.
See:
http://lcweb.loc.gov/marc/languages/

Note that the reason "sgn" was not included in ISO 639-2 is that the ISO
list was essentially frozen after the 1993 Berlin meeting of the ISO 639-2
Joint Working Group (except for resolution of some items from the
balloting process at various stages). The sgn code was approved for use in
MARC in late 1995.
