A question for the following text in section 5.7 (page 64): does it mean "the transient state when an RND flag is being established" (as shown two paragraphs later)? "When an IPv4 header is present in the static context, for which the corresponding RND flag has not been established to be 1, packet types R-1 and UO-1 MUST NOT be used." Br, Zhigang
