I ask your forgiveness for rehashing an old (a few days old) topic – the suggestion that James Snell made for using a media-type profile to distinguish between an entry’s children and an entry’s descendants. I think I get it but want to run this by the group for confirmation.
In the following (from James):
> <link rel="down" type="application/atom+xml;type=feed;profile="" href="" /> <link rel="down" type="application/atom+xml;type=feed;profile="" href="" />
a value of profile="" is used to indicate that we want the children to be represented without any expansion and a value of profile="" is used to indicate that we want the children to be represented with a potential expansion. I confess that initially I thought that this wasn’t a mimetype issue, that we were talking about two different resources – the set of children and the set of descendants. But what is proposed here is far more elegant, and is nicely cast as a mime-type choice. The key is that the link relation “down” only ever returns a child (as application/atom+xml;type=entry) or a feed containing_only children_ (as application/atom+xml;type=feed) – what differs is the representation format of that child (expanded or not).
And yes, I understand that the mime types and profile designators are most definitely outside the scope of this I-D.

Based on feedback, I have simplified the I-D to:
In-line extensions moved to draft-mehta-atom-inline
Removed down-tree and up-tree relations
Removed cardinality restrictions on up and down links
I am also tracking open issues about this I-D publicly at http://code.google.com/p/atom-ext/issues/list. The source for this I-D is also available, if you are interested.
Looking forward to comments on the I-D.
