The definition of "programmatically determined" most recently accepted
by the Working Group is as follows:
<currentDefinition>
Programmatically determined:
Can be recognized by user agents, including assistive technologies, that
support the technologies in the chosen baseline.
</currentDefinition>

I hope this is somewhat less opaque.

Even with the glossary, "programmatically determined" is horribly,
horribly opaque.  Even for native English speakers.  Even for native
English speakers who are familiar with 508 and WCAG1.  But that is a
topic probably best left to another time and thread.

I am not sure the glossary is the best place to address this, but a
solution to the question of validity as Level could be as easy as the
following amendment:

<blockquote>
Programmatically determined means that the specific value can be
determined in a standard, machine or software readable form.  For
example, content must pass validity tests for the version of the
technology in use (whether it be conforming to a schema, Document Type
Definition (DTD), or other tests described in the specification).

Yes, exactly correct!  The *omission* of a caption (or whatever) can be
programmatically determine.  Okay, so maybe the language isn't the
barrier I worry that it might be.  Not that I have any good ideas about
how to address that if it is a problem...
