Thanks for those kind words! And for the encouragement to consensus. 

I have now made an effort to bring the two CPs closer to each other. 
The CP is located at the same address but now has the following title:

   "@title is only a last resort source for text alternative
    repair - authors must not rely on such behavior"

where the last part of the sentence is a quote from HTML5.

Main changes: 

* I have copied lots of Steve's text into the CP - I hope he is OK with 
that.
* I added more critical remarks about Webkit. 
* I accept as premise that @title alone should not make the IMG 
conforming.
* The summary is new.

Compared with Steve's proposal, there is now less difference, however I 
still give weight to author's possibilities to make @title displayed 
via CSS and I point to WAI-ARIA's systematic access to @title when @alt 
is lacking - though I now balance with the fact that most authors would 
never do this. As before, I thus give more positive weight to Webkit's 
behaviour (which seems possible to replicate in Opera and Firefox with 
a little help from the author), but I balance by mentioning Webkit's 
well known problems of displaying @alt properly at all as well as 
expanding on some of the problems described by Steve related to getting 
@title to display when image is not displayed - @title is far from as 
(technically) reliable as @alt. 

The CP now, thanks to the things I took from Steve, gives attention to 
both keyboard access and "fallback repair access". 

Of course, Steve is welcome to borrow from my CP as well. I feel that 
the CP now gives a true picture of the @title status. But I of course 
open to corrections and changes etc.
