>   It could just as easily describe a PCE.

PCE could be a controller just talking to headends and asking them to 
signal LSP X with RSVP-TE or it could talk to all head, tail and via 
nodes and actually program the forwarding label entries.

I am observing that IRS framework is more of the former case rather then 
the latter in general.

However if this is the former then I am a bit not clear what value it is 
to deliver if we compare it with current statefull PCE efforts ;)

Best,
