That seems like a fine goal, but the draft is pretty vague about that. As  
far as I know it is undefined in the draft what  
`list-of-format-definitions` actually is. From the definitions it is  
unclear whether or not the colon is part of the image(<media-type)  
contract. It is unclear what a <media-type> is. It is not clear what  
font(truetype), font(type1) and font(opentype) actually represent. What  
does it mean for `font(image/svg+xml)` to return true? Or for  
`script(image/svg+xml)`? One of the examples states that `image/svg+xml,`  
(note the comma) must return true by compliant viewers. Is that  
intentional? What it means for a namespace to be understood.

It's entirely clear what happens with:

  requiredFormats="image/svg+xml foo/bar"

... given that the application does not support foo/bar.

http://www.w3.org/mid/41eb29e0.75649406@smtp.bjoern.hoehrmann.de seems to  
have a list of related questions which was e-mailed in Januari 2005. As  
far as I can tell from the list archives (searching for topic) there has  
been never a formal reply from the SVG Working Group to that e-mail. I  
hope all the other comments on the first Last Call have been replied to  
and addressed in the second Last Call document if necessary...
