Hixie replies again
Hixie has answered my question. Judging by how long it took IE to support CSS1, he estimates 6 years until XHTML is ready for main stream use. He’s almost certainly right, but I’m going to try to stick with XHTML any way (bandwagon jumping can be fun). He also points out that this site does not validate—I checked the original template but it seems that several of the entries I have added have inadvertantly invalidated the page, mainly through unescaped ampersands and the like. Time to add an automatic “validation” system to my administrative tools—it’s a shame the W3 validator isn’t available as a web service.
Thanks for the educational exchange Hixie :)
