GL 1.2, L1 SC1 and L2 SC 1: Captions

I took a stab at the Guide Docs for the two success criteria for
captions. 

I'd like feedback on the following:

- I have L2 SC1 reference L1 SC1 for techniques and references, since in
both cases we require captions; only the characteristics of the
multimedia (prerecorded vs live) are different. Does this seem ok, or
should the information be repeated in Guide Doc L2 SC1? Should more of
the sections of L2 SC1 just reference L1 SC1?

- Do we need discussion or techniques for what makes good captions,
parallel to discussions about what makes good alt text? Is it ok just to
reference existing resources on the web?

- It seems like the techniques need to apply to the multimedia
technologies, i.e., there is no HTML technique for captions. Does this
seem right?

- There is no SMIL techniques document. I tried putting the SMIL
techniques in-line in the Guide Doc. Does this seem ok? Is it ok to
include SMIL techniques here when we don't include them for other SC
such as GL 1.1?
