[Spellyans] IANA language code for SWF Cornish

[steve at chygwyn.com]

Hi,

I hope this question isn't too off-topic for this list... The IANA
(Internet Assigned Numbers Authority) maintains a list of language
codes including Cornish:

http://www.iana.org/assignments/language-subtag-registry

The entries include:
kw
kw-uccor
kw-ucrcor and
kw-kkcor

Does anybody know if there is a code for the SWF, or if one
has been applied for?

I'm trying to find out what the correct tag should be for
SWF Cornish in web pages and also for naming locales for
translating software,

Steve.
