Dear Synchronized Multimedia Working Group,

  http://www.w3.org/TR/2005/PR-SMIL2-20050927/ duplicates some text, one
example is the definition of the beginEvent event

  This event is raised when the element local timeline begins to play.
  It will be raised each time the element begins the active duration
  (i.e. when it restarts, but not when it repeats). It may be raised
  both in the course of normal (i.e. scheduled or interactive) timeline
  play, as well as in the case that the element was begun with a DOM
  method. 

and

  Raised when the element actually begins playback of its active
  duration. If an element does not ever begin playing, this event is
  never raised. If an element has a repeat count, beginEvent only is
  raised at the beginning of the first iteration. The beginEvent is
  delivered to elements which support timing, such as media elements and
  time containers, and does not bubble.

I am not sure why it does that (it seems like this is duplicated for
each profile), but these are 3 slightly different definitions and can
easily be confused; there are also problems like that the first
definition does not define the intrinsic bubbling behavior of the event.

I think these events should be defined just once; if there are profile-
specific considerations these should be called out explicitly for the
profiles.
