	4. IANA Considerations		4. IANA Considerations
	This document has no actions for IANA.		This document proposes to extent messages defined by the
			experimental Context Transfer Protocol [10] for the sake of
			supporting Multicast control. To achieve such a support the Context
			Transfer Data (CTD) Message and the Context Transfer Data Reply
			(CTDR) Message shall be modified to enable transfer of multicast
			related data, i.e. M-CTD and M-CTDR. The such transported data
			consist of subscription states and flags indicating specific actions
			to the PMIP defined anchor MAG. Such extensions described in sect.
			3.1. of this draft may require an allocation process by IANA as
			already described in [11].
