This is basically being discussed for "select editable", but no solution 
has been found that suits all needs,

  - backwards compatible
  - forward compatible
  - implementable
  - semantic

and therefore there hasn't been looked into this yet I suppose. Having a 
comma separated list might work, but is probably too technical for most

Single. Just see all the weblogs, login forms etc.
