If there's no difference between
  content: none;
and
  display: none;
then I don't think 'none' should be an accepted value for 'content'.


Also, 

  If CSS3 extends 'content' to real elements, its initial value
  must be 'auto' (self), not 'none' (nothing). Therefore, the
  initial value of 'content' in CSS2 cannot be 'none'.

  To avoid the problem I described earlier, either
     - CSS2 must define :before and :after not to exist in
       the presence of replaced content, and remove the
       image + alt text example,
    or
     - the initial value for 'content' in CSS2 must somehow
       invoke "display: none" so that the box for :before/
       :after disappears. CSS can define 'auto' to do this
       for :before/:after or leave out the value's literal
       representation entirely.

I'd go with 'initial' for CSS2 border-color, if anything. It
seems more sturdy than guessing at the future CSS3 Box Model.
