I just updated the Quirks mode and strict mode page. I added a bit about the "almost strict mode" and test pages for font sizes in TDs.

I also found one new problem in the validation drive: most of my large compatibility tables liberally use the <wbr /> tag, which is invalid. I acknowledge the problem, I will note it in the validation texts, I will remove all other validation errors, but right now I'm not going to do anything more.

Like custom attributes, the <wbr /> tag requires some more thought. As my research shows, this tag is the least bad alternative for adding soft word breaks to pages; and the compatibility tables badly need soft word breaks.

For reasons I explain below this site will never be 100% valid, but I have decided to make an effort and see what happens next.

Besides, my content pages are long, long overdue for a cleanup, and I'm going to combine this sanitation with the switch to XHTML. Unfortunately the very first static page I edited gave raise to a fundamental question that I don't have an answer to. Therefore I submit one aspect of the maintenance of QuirksMode.org to a reader vote.
