New submission from Basavaraj Patil <[email-masked]>:

Throughout the document, I find myself confused about whether a section is
talking about a system with Mobile-IP implemented in the kernel.  For example,
3.2.1 says

  The received ancillary data object for Home Address destination
  option SHOULD contain the Care-Of-Address of the mobile node.
...
  Note that whether or not these new APIs are used, the senders home
  address is contained in the source address

However, if the kernel doesn't implement Mobile-IP, then the HA option will have
the HA, and the IP source address will be the COA, right?

Another example is:
    For TCP data packets with Home Address destination option may be
    used with "sticky" option for all transmitted packets. However,
    at this point, it is unknown why an application  would want to
    set Home Address option or Route Header Type 2 extension header
    along with its data packets as Mobile IPv6 protocol takes care of
    them transparently at the protocol stack.
[written assuming that there's a mip6 stack]; vs. later in the document,
      However, some
  embedded software implementations may require to implement the IPv6
  packet processing/sending at the user level; those implementations
  may choose to provide API spport for sending home-address option
  at the application layer.

I think it'd be nice to see clear statements about which parts would and
wouldn't be used when there is or isn't a mip6 implementation in the stack. 
Right now it's very wishy-washy, sometimes saying things like "this is handled
by the mip6 stack" and sometimes saying things like "however you may have to do
some other stuff".
