request for subtag for Elfdalian

I also got problems again now because I wanted to upload the Elfdalian
keyboard to XKB <> (Xorg keyboards) to make it
available for linux users, as there are 7 extra letters needed to be able
to write Elfdalian, however it seems like we're only allowed to add ISO 639
codes, not BCP 47.

I have one question: How extensive is BCP 47 used?

With a language subtag it will of course be great to finally be able to
organize website content in Elfdalian, and to better identify Elfdalian
texts online, however it seems like the rejection of an ISO language code
still can undermine a lot of digital language development for Elfdalian.
The RA wanted to see "*that there would be serious separate language
development, apart from that of Swedish.*", but now in fact it seems like
their own decision are preventing exactly that kind of language development.
