#2 is not how atom:author "inheritance" works (assuming there is some kind
of atom:author inheritance, which is not established). I'd prefer #2 to be
equivalent to this:
<feed>
<entry>
<link rel=".../in-reply-to" href="{url2}" />
</entry>
</feed>
That is, the set of entry level links overrides the set of feed level links.
If I understand correctly, ".../root" tells you where to find the entry
identified with ".../in-reply-to". How are you dealing with multiple
in-reply-to?
<link rel=".../root" href="feeda.xml" />
<link rel=".../root" href="feeda.xml" />
<link rel=".../in-reply-to" href="tag:entry1" />
<link rel=".../in-reply-to" href="tag:entry2" />
If I misunderstood, what is ".../root" for?
