Just a few quick MathML examples here, stolen from Mozilla's MathML Torture Test page. This is only to demonstrate how you can seamlessly embed MathML XML markup directly within a XHTML document, in a Joomla! article. Note that you must serve your content with a suitable MIME type to just mix it into the document this way, and of course your browser needs to know how to render it.

You might as well forget Internet Explorer for this; it can't even handle some basic XHTML and CSS standards properly, least of all extensions such as MathML. But I believe there is an IE plug-in for MathML somewhere, and there are other tricks you can use (e.g. a special XSLT transform) to help out other browsers.

Opera has some limited support for MathML since 9.5 apparently, but as far as I know, Safari & Chrome are still lacking.

∴ Firefox = King of the Web :P

I made some changes to the identica Badge script the other day. It started out just wanting to make it work in a XHTML DOM, but I ended up hacking it to produce valid XHTML and CSS as well as couple of other small changes. Honestly, I can't think of a good reason that the script needs to pass validation - the changes to ensure it's output is well-formed were necessary, but that's about it. Still, I did it anyway, and then I decided to write an article as a kind of walk-through of the modifications.

Why? No particular reason. Despite appearances perhaps, I'm not just desperate for content here :D In part it's because the web as a reference source currently relies on having mountains of (largely redundant) information to say the same things in different ways given a multitude of individual and specific contexts. And the reason I did this at all is simply that Open Source relies heavily on vested interests; I wanted to make it work on my pages, to make it output valid markup, and I wanted it to be fluid width.

Looking for some nice people with OpenIDs to help me test this comment plugin...

I've noticed the occasional error when logging into Joomla! using OpenID with my own account, so I'd like to know if the problem is peculiar to me, or a more general issue. Please just add a comment below (click the article title first if coming from the front page) if you'd like to help.

Thank you!

Well, I finally got around to it. Every page here is now valid XHTML+RDFa, an extension of XHTML 1.1 (strict) that allows RDF meta-information to be added directly to the XHTML markup inline. I've started trying to add some SIOC markup to the new comments plugin that I'm building; the SIOC is neither complete nor 100% correct right now, but at least I've made a start :D
