RSVP-TE question

I need some clarification on the role of PATH and RESV messages while
setting up an LSP with QoS requirements. The draft talks about use of PATH
messages for verification of available bandwidth at a particular priority
and possible pre-emption of lower priority reservations. Could the PATH
message be used to hold QoS resources as well ? If yes, then what role does
RESV message play (in regards to setting up QoS) ? If no, when do QoS
resources actually get reserved ?

Thanks,
