jim, all,

in section 5.3, would it be possible to detail the
real scope behind the following paragraph:

"Providing a feedback mechanism in the reverse flow messaging of 
 RSVP-TE or CR-LDP signaling in MPLS to report on actual topology 
 state information such as link bandwidth availability."

more precisely, detail the relationship between "signalling
in mpls" and the report to "actual topology state information" 
since there are imho several ways to interpret the above 
sentence

thanks,
- dimitri.
