How about simply introducing a @generator attribute:
<img generator='foo' alt='' src=bar.jpg />

Instead of a validator exception, how about simply let the validator
split the validation results in several parts based upon who the author
is? Here is an example report which identifies two document
* Main author report:
No alt errors detected.
* Report for generator 'foo':
10 valid images but which the main author has not verified yet.
Here I assume that that verification flag is the *lack* of the
generator attribute. I.e. when the main author somehow blesses the @alt
text, then the generator is removed.

This is easier to avoid if the validator identifies responsibility -
