The final `` in [`recentchanges.tmpl`][tmpl] gets wrapped in a `

` tag for some reason, resulting in the following invalid XHTML at the end of the [[RecentChanges]] page

Also, there is a problem with the `` tags generated by the smiley plugin which end up wrapped in a `
` tag in the inline diff output.
`` tags is not allowed within a `
` block.  Maybe the smiley
plugin should be disabled on [[RecentChanges]]?

See the [validator output][validate] for more details.

I'll add this here since it's related.  I also noticed that the meta tags for
redirected pages need to be closed in order to be valid XHTML:

    

I'm noticing these problems because I'm serving ikiwiki-generated
content as `application/xhtml+xml` (as opposed to `text/html`) in order
to include inline MathML.  Any invalid XHTML causes Firefox to halt all
processing and throw an error. —[Jason Blevins](http://jblevins.org/)

Here is a simple patch for the refresh problem.  I haven't figured out
what's causing the recentchanges bug yet.

It turns out that the invalid XHTML on the recent changes page is due to
a bug in Markdown.  I was using the packaged version of markdown in
Ubuntu (Gutsy and markdown 1.0.1-6).  Everything is fine
after installing the most recent version of Text::Markdown from CPAN.

Note that the above patch for the redirect tag is still applicable and
the smiley issue remains open. --[[JasonBlevins]]
