Hi Tony,
You are correct in that a prefix can only be associated with one Flexalgo.
I will add some text about applications in the next version.

Ron,
This is nice. It makes it clear that constraint based path computation need not
have MPLS overhead for those that don’t want it.
One thing that you don’t talk about is how this gets used, tho that may be
blindingly obvious: you’ll need all nodes placing their prefixes in the
RIB/FIB, where it will need to be selected over other path computation for the
same prefixes. This somewhat precludes the possibility of a given prefix being
useful in multiple flex-algos.
More text on application would be most welcome, just to ensure that we’re on
the same page.
Tony
