This makes it clear that we are talking about "here is how you do it", rather than "here's one way to do it".
We might be treading on toes making that assertion.
Yes, but it's not only correct, it's good advice, so we should put it in.
4) Add a sentence saying something like "Feeds or Entries are identical if their IDs compare identical.". Seems obvious, but isn't stated anywhere.
No. Feeds/entries with the same id are different versions or instances of a common ancestor. They are not "the same".
Graham's right, the word "identical" is wrong, because in fact you will commonly encounter two instances of the same entry which aren't identical (e.g. the one in your cache and the one you just fetched). I suggest "Software MUST treat any two entries which have the same ID as instances of the same entry, regardless of how they were obtained or any differences in their content." Or if you want it less prescriptive "By definition, any two entries which have the same ID are instances of the same entry, regardless of how they were obtained or any differences in their content." -Tim
