COMMENT:

Thanks for this, I found it clear and easy to read. I have just a couple
comments.

Hi John,

Many thanks for the comments - please see the updates in version -11 which was just published, which we hope address your comments.


1. In §5.2, there is

Servers MAY defer processing of a query until the STREAM FIN has been
indicated on the stream selected by the client. Servers and clients
MAY monitor the number of "dangling" streams for which the expected
queries or responses have been received but not the STREAM FIN.
Implementations MAY impose a limit on the number of such dangling
streams. If limits are encountered, implementations MAY close the
connection.

Wouldn’t a stream be dangling even if the expected queries and responses hadn’t
been received? I.e., isn’t the thing that makes a stream “dangling” simply the
lack of a STREAM FIN?

We’ve updated the text in 5.2 related to dangling streams so please review to see if this clarifies the issue?


2. In §5.4,

Client and servers
that send packets over a connection discarded by their peer MAY
receive a stateless reset indication.

This seems like a misuse of the RFC 2119 MAY. Do you mean "may" or better
still, "might" or "could"? If you really mean the 2119 keyword, then a rewrite
seems to be in order to put this in terms of the other party being permitted to
send the reset.

We’ve changed MAY to might - thanks!

Best regards

Sara.
