the_category() function in WordPress generates some invalid markup by creating an anchor tag with a rel attribute that looks like "category tag" (see the markup for the "Uncategorized" link here).

It seems the problem is category is not a valid value, and also it should be one word.

Most people are deleting it completely, but I was looking at the list of valid values and was wondering if any of them would be appropriate for a link to category page (such as this one)?

In particular tag, section, and subsection caught my eye, but their intended uses are not clear to me.

category and tag are valid values. Some validators are not up to date.

tag is defined in the HTML5 spec.

category is listed at http://microformats.org/wiki/existing-rel-values#HTML5_link_type_extensions, which is the normative registry for link type extensions.

If both link types apply, it's correct to separate them with whitespace.

Note: don't use these link types on any link to the category/tag page; only use it where the linking page is categorized/tagged with the corresponding category/tag. So a page listing all categories shouldn't use the rel value "category" for the links.
