aloha, jon!

i agree with jon that the proposed change to 2.1 needs to be explicitly 
stated, and i'm leaning towards endorsing the view that the user needs to 
have access to ALL alternative equivalents through the user 
interface...  providing a fall-back mechanism within the user agent is a 
far bigger accessibility gain than relying on an API alone to expose 
alternative content -- especially since there will (for the foreseeable 
future, at least) be many cases where a particular API either isn't 
supported or doesn't yet exist...

it falls under the classification of a clarification, as i don't see the 
HTML 4x rec forbidding complying user agents from enabling the user to 
expose the content of NOFRAMES, merely an explicit statement that when 
configured to display frames, the user agent should not also simultaneously 
render the content of the NOFRAMES declaration...  it clearly implies that 
users could be offered the choice between rendering frames and NOFRAMES, 
but doesn't proscribe their exposition (as an alternative to frames) 
according to user preferences, so i don't perceive a conflict between the 
HTML 4x rec and UAAG checkpoint 2.1, as proposed...

i also think, as i repeatedly stated at the last telecon, that as far as 
2.1 is concerned, the question of a source view satisfying the point is a 
red herring...  it's a great thing to have, and i personally wouldn't use a 
tool that lacked one, but it doesn't satisfy UAAG 2.1
