	I support the removal of section 2.5.5 and section 2.2(3).
	IPv4 compatible address is not used any more as auto tunnel went away.
	my position on IPv4 mapped address is described in the following
	documents:
		draft-cmetz-v6ops-v4mapped-api-harmful-01.txt
		draft-itojun-v6ops-v4mapped-harmful-02.txt
