Section 3.1, paragraph 3: "when the initiator is the mobile node" -> "when 
the initiator is a mobile node"

Section 3.2: I think the explantion around the messaging sequence needs to 
indicate that the addresses which the initiator can switch between are 
included in the SAi2 and SAr2. When I read this, I found myself asking "how 
can the initiator switch addresses when no alternate addresses are given?" 
We otherwise do not find out that the addresses are in the SA until much 
later in the document.

Section 3.2, first paragraph after messages: This paragraph describes what 
1)-3) do, but not 4). You may think it obvious, but it should be included 
for completeness.

Section 4.3, paragraph 4: "The responder normally..." The document makes a 
big point about "initiator decides", then throws in this little caveat. For 
example, in this paragraph, it goes to great lengths to describe how there 
is a policy module of some kind on the initiator that makes the decision 
about what address to use. When it comes to the responder, however, it says 
the responder doesn't use the addresses, except... When you think about the 
"except...", however, you need to ask yourself: "Well then wouldn't the 
responder have an equally powerful policy module that would determine when 
an address goes down and when it then tries to use another with the 
initiator?" In effect, the protocol really isn't "initiator decides", 
because the responder can, spontaneously, decide to use a new address pair 
too. I might be missing something here, and therfore it might make sense to 
actually include a specific, bulletized list about what the initiator and 
responder can decide about using an address pair. This would actually 
clarify what "initiator decides" really means.

Section 4.4, first paragraph: same comment as above w.r.t. responder's 
ability to change address.

Section 4.4, after second bulletized list: "When the initator receives the 
reply, it:" -> "When the initator receives the reply, it does the 
following:"

Section 4.4, third bulletized list, third bullet: "initiator MAY select 
another addresses" -> "initiator MAY select another address"

Section 4.4, paragraph after third bulletized list: Same comment w.r.t 
responder decision.

Section 4.5, paragraph after first message sequence: "the exchange 
responder:" -> "the exchange responder does the following:"

Section 6.1, paragraph 3: "lead the peers believe" -> "lead the peers to 
believe"
