Validity of feeds consisting solely of links

[Andreas Wuest <awuest@xxxxxxxxxxxxxxx>]

Hi

I am not sure about the validity of the following feed. According to the 
feed validator, it seems to be ok, but when looking at the spec, I am 
just not sure. The feed consists only of links to entries, instead of 
<atom:entry>s. But I assume a client should render a list with titles 
equally to a feed which consists of real entries.

<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="http://www.w3.org/2005/Atom"; 
xml:base="http://ulysses.wyona.org/atom/entries/";>
  <title>Ulysses Demo</title>
  <link href="/demo/atom/entries/index.xml" rel="self"/>

  <link title="ulysses-prototype-1-0.1.10-rc2-r16389.xml" rel="edit" 
href="ulysses-prototype-1-0.1.10-rc2-r16389.xml"/>
  <link title="ulysses-prototype-1-0.1.10-rc1-r16251.xml" rel="edit" 
href="ulysses-prototype-1-0.1.10-rc1-r16251.xml"/>
  <link title="ulysses-prototype-1-0.1.10-rc3-r16660.xml" rel="edit" 
href="ulysses-prototype-1-0.1.10-rc3-r16660.xml"/>
</feed>

Also, such a feed makes it rather troublesome for clients, especially if 
the links were mixed with real <atom:entry>s, because the client has to 
create "fake entries" out of the the links, and mix them with the real 
entries.

It would be nice if someone of you could clarify if such a feed as 
depicted above is actually a valid feed.
