When vector graphics is not considered as the user agent owner, but just one 
of the media that can cooperate in the creation of a presentation, then 
assumptions about the "vector graphics as owner of the user agent" are 
flawed.

I am not as stupid as you want to represent it. If you reread my message 
later, you will have to admit that I could not possibly mean to remove those 
items in the parentheses, namely "elements and attributes syntax, semantics, 
rendering model and specific APIs". I was rather suggesting to retain
onlythese items in the "vector graphics" profile.
