There are implementations (GMPLS for Optical networks) where this timer is set to 0xFFFFFFFF (to never expire)
Moreover, the psb list can only be used with config=false because it does not have a key: does this default value has any meaning?
Please also note that the session-attributes grouping is used only once as config=false. If it is intended to be re-used with config=true, the psb list should be marked as config=false.
