On the Structured Blogging mailing list the question keeps coming up on whether the plugins will generate valid XHTML. Well, until this is considered valid XHTML, I doubt they will.

I have a real problem with this as it severely restricts what you can do with XHTML documents. As far as I'm concerned the XHTML validator is broken. What's the point of converting the thing into XML, if you're going to simply make the use of XML extensibility mechanisms invalid?
