Hi Gorry and Tom,

Thank you for your replies. We have updated as requested.

Please note that we have some follow-up questions/comments.

moved into the <aside> element, or left as is?

Section 3:
   Note: UDP allows an Upper Layer protocol to send datagrams with or
   without payload data (with or without UDP Options). These are
   delivered across the network to the remote Upper Layer. When
   DPLPMTUD is implemented within the UDP transport service, probe
   packets that include a REQ or RES UDP Option can be sent with no UDP
   payload. In this case, these probe packets were not generated by a
   sending application; therefore, the corresponding received datagrams
   are not delivered to the remote application.

Section 3.3:
   Note: A receiver that only responds when there is a datagram queued
   for transmission by the Upper Layer could potentially receive
   multiple datagrams with a REQ Option before it can respond. When
   sent, the RES Option will only acknowledge the latest received token
   value. A sender would then conclude that any earlier REQ Options
   were not successfully received. However, DPLPMTUD does not usually
   result in sending more than one probe packet per timeout interval,
   and a delay in responding will already have been treated as a failed
   probe attempt. Therefore, this does not significantly impact
   performance, although a more prompt response would have resulted in
   DPLPMTUD recording reception of all probe packets.

) FYI, we will hold off on making these updates until we’ve received a response 
from RFC-to-be 9868 regarding this terminology.
