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.
