jp,

in fact the below list should simply be as follows for 
signalling-based methods: 1) constraint-passing 2) loose 
routing and 3) path query; 

and the for constraint-passing we have a several i-d's
such as, 

http://www.ietf.org/internet-drafts/draft-lee-ccamp-rsvp-te-exclude-route-01.txt 

constraint passing may also be extended using the crank-
back as listed below; the usage scenarios of these methods 
are described in the following:

http://www.ietf.org/internet-drafts/draft-kompella-mpls-multiarea-te-03.txt

now probably it is worth spending some time in considering 
input coming from the tewg wrt to this effort, most of the
input that you see listed above has been produced over the
past year (and more) i can't imagine stepping in the protocol 
details without a clear consensus on what do we want to cover 
within the ccamp wg & w/o taking into account the tewg rec's
(probably better to discuss this on the ccamp mailing list)

thanks,
- dimitri.
