+8.4. and others
+
+  8.3. and 8.4. define the *Transfer Proposal Message* and *Transfer
+  Proposal Receipt Message*. There are a number of message pairs with
+  similar pairs of names, with the second part being variously named
+  ... Receipt Message or ... Response Message.
+
+  Language along the lines of "The message is sent from the [recipient
+  gateway] to the ... EndPoint at the [sender gateway]" appears in
+  many if not all of them
+
+  It's never made clear if this just e.g. requires *Transfer Proposal
+  Receipt Message* as the form which the HTTPS response body should
+  adopt when responding to an HTTPS POST request in the *Transfer
+  Proposal Message* form or, as I read it at first, actually means a
+  _seperate_ HTTPS POST request in the *Transfer Proposal Receipt
+  Message* format is sent from the recipient gateway.
+
+  That is, are we being told about a single HTTPS exchange, or two?
+  Or is the intent to allow for either?  I think either at the
+  beginning of section 8, or somewhere earlier, perhaps section 6,
+  this should be explained.  Indeed Figure 2 in section 6 might
+  encourage one to think that the Transfer Proposal exchange requires
+  one HTTPS exchange, whereas the Lock Assertion exchange involves
+  two.
+
+11.
+
+  The discussion of time-outs and aborts leaves it unclear whether a
+  gateway which times out waiting at some point in a session should
+  send a session-abort-msg or not, but I would think it should.
+
+  Note that the phrase "time-outs due to gateway crashes" doesn't make
+  any sense: from the point-of-view of a gateway (G1) which times out
+  waiting for a response, there is no way to detect the _reason_ for
+  the timeout.  In case a timeout is _not_ because of a crash on the
+  part of the other gateway (G2), surely notification that the session
+  is being terminated by G1 should be sent, to enable an orderly
+  close-down by G2, instead of it having to time-out itself.
