Section: 7

Original Text
-------------
After decreasing the bandwidth, the ingress node
SHOULD send a ResvErr message to tear down the old control state.

Corrected Text
--------------
After decreasing the bandwidth, the ingress node
SHOULD send a PathTear message to tear down the old control state.

Notes
-----
PathTear is the usual mechanism to teardown old control state. This is would also make the bandwidth decreasing procedure consistent with the bandwidth increasing procedure (bandwidth increasing procedure uses PathTear to teardown old control state.)

This change looks like a change of substance, but the authors confirm that their intent was to use the same process for both the increase and decrease in bandwidth.
