So I'm catching up on my feeds today, when I spot one that seemingly has no content. This is odd, so I go to look at the feed source. There's no <description> tag! Ok, looking at the RSS 2.0 spec, that's technically legal. InadvisableIMHO, but legal. So where's the description? In a <content:encoded> - the namespace is defined, right at the top of the document. Easy enough to deal with - a quick modification to the Constructor code, and BottomFeeder is back in business.
The only thing is, I don't get it. What's the point of moving the description to a namespaced element? The namespace in question is part of the RSS 1.0 (RDF) module system, but - What's the benefit?
