Why do you ask, when the CP *does* suggest to have have a HTML5 
specific guide - in the form of Steve's alt techniques spec? Changing 
his spec to be a co-deliverable of the HTML WG and the WAI WG, does not 
change that it is a HTML5 specific text. That you also, at the same 
time, want to make it less normative, also do no change that it is 
HTMl5 specific.

If this CP was accepted, then how could there be any @alt text 
validation in the HTML5 validator? Would that kind of validation not 
need an extra step - e.g. a separate A11Y validation? The CP is 
critical about HTML5's options for not including the @alt attribute. 
But how does the fact that the CP suggests to 'Remove normative aspects 
of the techniques document', make a difference to that problem?

I think it would be great if the @alt text rules could be simplified. 
And in that regard, it has been claimed it is better to have short and 
clear advice rather than longwinded and intricate advice - which can be 
important too, but short and clear rules are also needed.

With regard to WCAG 2.0, then I don't have a problem with it, but have 
a problem with its normativeness: The general rules are normative, 
while the concrete techniques are only non-normative advice — one often 
gets to hear that it is just the opinion of those who contributed to 
the technique. It is confusing.

The good thing with a normative spec is that what it is says tried out 
and wetted more thoroughly than non-normative specs. At least, that is 
my perception of the effect of being normative.

I am not complete and forever opposed to having it in a separate spec 
and to make that spec less normative. But I see the above mentioned 
issues with the proposed direction.
