Re: Justification for HDLCPW and FRPW

Javi,

Because it's in L2tpext's Charter.

http://www.ietf.org/html.charters/l2tpext-charter.html
	II. L2TP Interaction with PWE3 for Pseudo-Wire Transport:
	In addition to tunneling PPP, L2TPEXT will develop protocol
	extensions necessary for the tunneling of specific
	"pseudo-wires" as defined in the PWE3 WG.

http://www.ietf.org/html.charters/pwe3-charter.html
	Specify the following PW types:
	Ethernet, Frame Relay, PPP, HDLC, ATM, low-rate TDM, SONET/SDH
	and Fibre Channel.
	...
	The PWE3 WG will do this in its entirety for MPLS PSNs, and the
	L2TPEXT WG will develop the L2TP specifics for L2TPv3-based PWs.

Thanks,

--Carlos.
