This is critical. What is the language identity? Is it at its core English or is it something else? If it's best seen as a variant of ASL / BSL / etc, then we should treat it as such; it it's best seen as a pidgin of English and ASL / BSL / etc. then it is a distinct language, related to but different from both.

It's not clear whether this is a sufficient criterion. If a typical English speaker were to see English transcribed or transliterated into Georgian script, they wouldn't understand it. Mind you, if it was read aloud, they'd understand it -- the phonology is the same; but in the Signed English cases the phonological representation itself is different.

The merits of potential language tags do not exist independent of such algorithms. Just as proposed character encoding cannot be evaluated independent of text processing issues such as rendering and sorting.

I'm inclined to believe that, linguistically, signed languages aren't all that different from oral languages. They present their own challenges wrt technology, but as far as *identification* is concerned, I don't believe the issues are likely to be that different.
