XHTML 1.1

I “upgraded” this blog from XHTML 1.0-Transitional to XHTML 1.1. The idea is that if I ever decide to take another stab at dabbling in MathML, it’ll be an easy transition.

XHTML is modular, and the W3C has already published an XHTML 1.1+ MathML+SVG DTD. You can also load other standard modules into your DTD, e.g. for frames or for the “target” attribute. I can finally say truthfully that the whole weblog (including the MathML stuff) validates.

All in all, it wasn’t too bad a transition: a few modifications of the templates to eliminate some deprecated constructions, and a bit of fixing of some old entries. XHTML 1.1 is stricter than XHTML 1.0 about what can go inside a <blockquote> and insists that

<div>
<form>
...
</form>
</div>

be rearranged to

<form>
<div>
...
</div>
</form>

Holler back if something broke for you, but it seems to me that anyone whose browser can handle XHTML 1.0-Transitional can handle XHTML 1.1 just fine.
