I mentioned this once before:
http://www.htacg.org/tidy-html5/
While Tidy died in 2008, this fork lives on and is HTML5 aware. That will at least solve a lot of problems *caused* by Tidy, such as not allowing block elements inside inline elemensts (which is allowed in HTML5).
Can we at least evaluate if this is a suitable interim solution?
