Magnus: Thank you for your time looking at my review.
More inline; I will cut the extraneous text below and retain the text that provides context.

It is intended to generalize it so that it works in cases it has
multiple IP addresses. However, the main point is that traffic related
to one RTP session can flow across multiple UDP flows, independent if
there are one or more IP addresses involved.
I guess that last clarification could be added in a new sentence before
the one that starts with "Another example ...".
Sounds good.

I agree that whatever is not the best term. However, I think artifact is
the wrong term. Looking for example at Merriam Webster's definition it
sounds wrong:

NEW:
The term "format" here includes those aspects described by out-of-band
signalling means; in SDP, the term "format" includes media type, RTP
timestamp sampling rate, codec, codec configuration, payload format
configurations, and various robustness mechanisms such as redundant encodings
[RFC2198].
I will leave it to your sound editorial judgement above. Personally, I think artifact is fine as it denotes a by product of a particular human endeavour (multimedia protocol design). But I am fine with "aspects" as well, as you suggest. Certainly, both these choices are better than the original wording.

See your point. In some cases it is the user or a system designer.
Great, thanks.
The below nits we will go through and update the document.
Sounds good. Thanks again for your time.
