Re: [fxtf-drafts] [filter-effects][compositing] What is "no-composite" blending?

I'm not sure I follow. Blending itself doesn't composite. (The original spec broke this out but that was removed to get to CR which makes it a bit confusing.)
For the usual case, blending calculates a new source color with the following formula: 
   Cr = (1 - αb) x Cs + αb x B(Cb, Cs)
with B the blending formula.
This new source color is then composited as usual using source-over.

For a no-composite filter, you just execute the blending step.
