Thank you for documenting the WAI CG consensus.

I have three questions related to software generating <img> elements:

  1) The user creates a new HTML document in an HTML5-compliant future  
version of a Dreamweaver-like product and saves it with a name. The  
user then drags an image file from the Finder onto the document window  
and the image is inserted into the document. The user presses command- 
S and then command-Q. What attributes should the generated <img>  
element have?

  2) The user takes a photo with his/her cameraphone and uploads it to  
a service such as Brightkite. The user has the option to add an SMS- 
like short caption that will be rendered in addition to the photo in  
visual browsing settings but is not forced to add a caption. What  
attributes should the generated <img> element have when the photo  
appears immediately on the Web? (Brightkite now says alt="Photo-feed".  
Reference: http://brightkite.com/objects/80d0f32c11e311deab31003048c10834)

  3) Point #5 under "Use Case 2 (author using a photo sharing site)"  
instructs photo sharing sites to generating alt="Photo 1 of 50 of  
album Paris 2009". Why is this approach recommended instead of  
generating aria-posinset="1" aria-setsize="50" and an alt attribute  
that doesn't repeat the set position data, e.g. alt="Paris 2009"?
