It's not necessarily true that the sign language video would *always* be
"an alternative to something else." A Deaf author might create a site
whose primary natural language is Sign, and whose primary medium is
video. (See, for example, Guidelines for Signing Books, an EU project
from the late 90s, at
http://www.sign-lang.uni-hamburg.de/signingbooks/SBRC/Grid/d71/guidein.h
tm.)  If the Sign language used in the video does not have a language
code, I personally think 3.1.1 and 3.1.2 could be satisfied by using a
properly *registered* language code. 

In such cases, Sign language interpretation would go from Sign to
speech, which could then be transcribed and published as a partial text
alternative  (I say "partial" because additional description might also
be needed if the video includes other visual content necessary for
understanding the signed content).

I offer this as personal opinion.

Quoting cstrobbe <Christophe.Strobbe@esat.kuleuven.be>:
<quote>
Suppose you have a video or a video stream with just sign language, 
what technique would you use to make the (primary) natural language 
programmatically determinable? (Leaving asside the issue that not all 
sign languages may have language tags.)

I looked at it once more. The sign language video would already be an 
alternative to something else. The solution seems to be to fall back on 
SC 4.2.1 (situation B in 'How to Meet SC 4.2.1' [1]).
