RDF feeds contain invalid tags, "category".

[kztk]

RSS1.0 feeds contain invalid tags, "category".
For example, a RSS1.0 feed includes following.

  <dc:subject><![CDATA[SomeCategory]]></dc:subject>
  <category><![CDATA[SomeCategory]]></category>

A patch to "wp-includes/feed.php"

You would be correct if we'd be generating RSS 1.0 feeds, but we're generating RSS 0.92 feeds, which do allow <category> tags.

See: ​http://backend.userland.com/rss092

[kztk]

But, this function is called with an argument "rdf" from "wp-include/wp-rdf.php" to generate RSS1.0 feed.
I think it is a problem.

In case of generation of RSS0.92 feed,
get_the_category_rss("rss") is called to generate "category" tags.
So, I think, my change does not change the generation of RSS 0.92 feeds.

[Nazgul]

You're right. I hadn't taken RDF into account.
