Changed:

	<t>In the first message of an initial IKE exchange, the
	initiator will not know the responder's SPI value and will
	therefore set that field to zero. When the IKE_SA_INIT
	exchange does not result in the creation of an IKE SA due to
	INVALID_KE_PAYLOAD, NO_PROPOSAL_CHOSEN, or COOKIE (see <xref
	target="sect-2.6" />), the responder's SPI will be zero also
	in the response message. However, if the responder sends a
	non-zero responder SPI, the initiator should not reject the
	response for only that reason.</t>

Not sure where it could point, so I removed it. And there you can also
see why it is not so easy to see it points to section itself :-)
