| Considering that the describing a structure for XML and ensuring
| that documents conform to that structure is generally a solved
| problem I find it perplexing that no schema for RSS (besides an RDF
| schema) exists.

The RSS 0.91 specification from Netscape had a DTD:
  <URL: http://my.netscape.com/publish/formats/rss-spec-0.91.html >

Given that RSS 0.91 did not enforce a particular order on most
elements XML DTDs were not a particularly good fit, but they used it
anyway, probably because they had an example to start from.

Why the later versions didn't have any sort of formal schema I can't
answer. I wondered about that, too.
