Re: [syndication] Re: locating syndication feeds

[Mark Nottingham <mnot@mnot.net>]

I thought about this for a while. My original motivation was saving
space; if you had more than one feed of a particular format, you
wouldn't have to reiterate the URI. However, I'm currently thinking
that only one instance of a particular format should be allowed, so
this isn't the case any more.

That having been said, I don't know this is a "bad" use of
namespaces; the only thing that a namespace guarantees is the
uniqueness of a qualified name within *that* document. Anything else
(including 'permission') is pure conjecture. I'm no namespaces
expert, and I'd like to talk to a few people to get a feel for this,
just to test the theory.

At any rate, something like an attribute is probably more
appropriate; the easiest win is that it makes using XPath to find a
channel possible.

Cheers,
