Sorting algorithm with SVCB/HTTPS RR

[nidhijaju]

We should add text about the sorting algorithm incorporating SVCB/HTTPS RR.

One option (that an existing implementation has already been using) is to prefer addresses received in hints or resolved via service names on SVCB/HTTPS records over direct A and AAAA responses, and sort the SVCB/HTTPS derived addresses based on their priority.

Right. I think the hints in SVCB should be the same as the A/AAAA derived from SVCB, but our implementation does prefer any SVCB-based (hint or query) address over the "plain" A/AAAA answers.

+1 we should specify how to do this - that way all clients will have the same preference, allowing servers to rely on it.
