    Not quite.
    
    Unknown elements in the Atom namespace make the document invalid
    Atom.

    Atom allows stuff from other namespaces, that's how you extend it.

    I'm aggregating, creating new Atom feeds from different sources.
    I've saved the entries in files. Some of the entries have
    unpredictable extention namespaces.

    Ideal output...

    <atom:entry atom:xmlns="http://www.w3.org/2005/Atom";
                xmlns:sw="tag:somewhere.com,2005:/extra">
      <atom:id>tag:somewhere.com,2005:/feed/article</atom:id>
      <atom:link
        rel="alternate"
        href="http://somewhere.com/feed/article</atom:link>
      <sw:extra-info>I like cheese!</sw:extra-info>
      <atom:updated>2005-09-20T20:32:10Z</atom:updated>
    </atom:entry>

    Where I'm at now...

    <atom:entry atom:xmlns="http://www.w3.org/2005/Atom";>
      <atom:id>tag:somewhere.com,2005:/feed/article</atom:id>
      <atom:link
        rel="alternate"
        href="http://somewhere.com/feed/article</atom:link>
      <sw:extra-info xmlns:sw="tag:somewhere.com,2005:/extra">I like cheese!</sw:extra-info>
      <atom:updated>2005-09-20T20:32:10Z</atom:updated>
    </atom:entry>

    The fix in the last post made it like the above.

    Where I was...

    <atom:entry atom:xmlns="http://www.w3.org/2005/Atom";>
      <atom:id xmlns:sw="tag:somewhere.com,2005:/extra">tag:somewhere.com,2005:/feed/article</atom:id>
      <atom:link
        xmlns:sw="tag:somewhere.com,2005:/extra"
        rel="alternate"
        href="http://somewhere.com/feed/article</atom:link>
      <sw:extra-info xmlns:sw="tag:somewhere.com,2005:/extra">I like cheese!</sw:extra-info>
      <atom:updated xmlns:sw="tag:somewhere.com,2005:/extra">2005-09-20T20:32:10Z</atom:updated>
    </atom:entry>

    So, I'm happier, but the first version would be "namespace
    normal", and that's supposed to be ideal. 

    Cheers.
