Note about exclusions model

My understanding is that what we resolved in [1] regarding
publication of css3-exclusions on the TR page meant that the
issue, described in [1] as:
 #    dbaron: Fundamentally I think the absolute positioning model is the wrong
 #            thing to tie exclusions to. I'd rather connect them to the floats
 #            model.
would be mentioned within the spec.

This mostly relates to the material in sections 3.4 (Exclusions
order) and 3.5 (Exclusions implementation note) of the
spec: http://www.w3.org/TR/2011/WD-css3-exclusions-20111213/

The issue that I wanted to be noted, could, I think, be described as
follows:

  These rules for exclusions order and exclusions on absolutely
  positioned elements (particularly those with static position)
  build this exclusions model on top of the absolute positioning
  model in CSS Level 2, rather than on top of floats, the existing
  exclusion model in CSS Level 1 and 2.  The CSS Working Group has
  not reached consensus on whether it intends to base the new
  exclusions features in this specification on top of absolute
  positioning (as these sections of this specification do) or on top
  of floats.

This proposed note completes ACTION-415.
