No. Signed English using ISL or BSL or ASL is essentially a special
form of ISL or BSL or ASL. It isn't really English. Fluent speakers
of ISL when confronted with Signed English using ISL or ASL can
understand it. Fluent speakers of English who do not sign cannot. We
call it Signed English because it stands in relation to written and
spoken English. But it is not English.

Such algorithms are not the reason we have language-tags, I am sure.

Thanks, Peter. It's "hare-brained" though, isn't it?

They aren't just like any other normal language. They're different,
and they interact with spoken languages in unique ways, and this
needs working out with the Deaf community.
