Some cleavage :
http://www.intertwingly.net/wiki/pie/NamespaceDiscussion
Note that the namespace cleavage has only appeared in this "simple" branch.
The RSS 1.0 branch uses namespaces extensively even for relatively simple
feeds, using standard terms like those of Dublin Core. There it just
works...
Some (moderately amusing) historical references to namespaces in Userland
RSS :

A lot of the arguments I've heard against XML namespaces end with "...but
I'll use them if I have to...", so I'm not sure about the toxicity. But in
the context of RDF they make so much sense I personally find it hard to
understand the objections. But (as has been joyfully pointed out here
before) RDF/XML is hardly typical XML. So is there a bad smell to
namespaces? Maybe.

I wouldn't characterise those as much aspects of RSS practice, rather of
certain practitioners. I don't think the CDATA stuff is quite as bizarre as
it seems - the motivation is to use HTML markup for content, but without
namespaces and XHTML this leads to a bit of a mess.

Heh, I agree with your conclusion but not your observations! The first one
anyway - there has been a continuous tug-of-war between developers that want
to do things as 'properly' as possible and those that want things to be as
'simple' as possible. There probably wouldn't have been any conflict if
'simple' hadn't used underspecification as a tool. The 'properly's have
often frightened the 'simple's when talking about standards, namespaces and
so on, and now the 'properly's are moving on with Atom. Meanwhile the
'simple' RSS 2.0 wagons have circled around some good stuff but also quite a
lot of garbage.
Cheers,
Danny.
