Hello Sam,

The responses to date have been "informal" - as the subject line had 
indicated. I am now reading your request as that for something more formal, 
which is cool, but also changes the request significantly.

This issue item has generated a significant amount of discussion in the 
past, discussion that I for one was an active participant in. I will not at 
this time revisit any of that discussion, but will happily do so if 

Based upon those discussions however, and in response to your specific 
question *I* will object to any ALT text repair 'technique' in the 
Specification that *does not* directly involve the content author, as only 
that author knows why an image is inserted into the page. This includes 
techniques such as OCR, Crowd-Sourcing, meta-data mining or the rolling of 
chicken bones - all being equally effective in determining author intent.

Specific to Maciej's original question (and your follow-up), this means I 
will actively oppose options:

 * Change Proposal: There is no problem and the proposed remedy is to change 

 * Change Proposal: Include more detail about possible image repair 

As the first Change Proposal states:
 "Removing the text[1] will not prevent UAs from implementing such a system, 
but will protect the importance of @alt from being undermined."

([1] Text by-the-way being *1 sentence*: "User agents may also apply image 
analysis heuristics to help the user make sense of the image when the user 
is unable to make direct use of the image, e.g. due to a visual disability 
or because they are using a text terminal with no graphics capabilities.")
