In <http://www.w3.org/TR/xhtml-basic/> (<http://www.w3.org/TR/2008/REC-xhtml-basic-20080729/>, to be precise), there are at least two typos, "settop" (AFAIK it's typically "set-top") and "implemententation". Apart from that, Alessio Cartocci's and Luca Mascaro's affiliations problably don't deserve two "li" elements each. ;)
