I've been thinking about the feed issue for a while now (obviously),
plus I've had a few e-mails with Benjamin and so forth. For a while I
was leaning toward depreciating or removing the feed element, but I'm
more or less back to where I've started, with one minor mod.
- feed is a part of Atom which suggests (but does not require) its
presence in hAtom
- feed is easy and harmless to add to templates
- conceptually, it's a good idea to group like things
- requiring an explicit feed element makes it easier to avoid
"accidental" name space collision
- multiple feeds on one page can be differentiated by the id/uri fragments
- if not expecting multiple feeds, the first feed can be considered the
feed for the page, even if others exist.
Although not covered explicitly in the examples, my latest thought is to
allow a Feed element to be embedded in an Entry element. Why? To model a
comment feed, which obviously is blog like content.
