Your proposal sounds really interesting, and perfectly "catching" most 
of the basic problems with the topic.
Just I'm not sure I fully understand what - validity as a necessary but 
not sufficient technique for all the success criteria that require 
something can be 'programmatically determined' -  means.

Roberto Scano:
I think is more clear if you read the definition of "programatically
determined":

<blockquote
cite="http://www.w3.org/TR/WCAG20/#programmaticallydetermineddef">
<p>programmatically determined means that the specific value can be
determined in a standard, machine or software readable form.</p>
</blockquote>

It is necessary because a software that render the page code must be able to
read it and identify elements and attributes that need a second level of
control.
For example, in the case of table, the caption is programmatically
determined but there is need to check if the caption is good... The same
with alt attribute, acronym, abbr and every element inside a page.
