What does this mean?
Every page should specify what language it is written in. The <html> element
should have a lang or xml:lang attribute which describes the language of the page.
Unless you are using XHTML, you will usually want to use the lang attribute as follows:
<html lang="en-US">Make sure you specify a valid language code.
