	Take a look at the slides from the meeting as they detail this, but in summary we would eliminate the router alert option. This reduces things down to 2 true modes of operation, and we could also attach some language that clarifies how and when to use both. 

	The more comprehensive approach would consolidate all of the existing RFCs/drafts including MPLS-TP. This would normatively redefine all CC Types, would define type 2 as obsolete, type 1 as mandatory for CW, type 4 as mandatory for non-CW, and a variation of type 3 (manipulating TTL) as for multi-segment only
