Trade off between best practice and practicality

The [Internationalization Best Practices: Specifying Language in XHTML 
& HTML Content]
(http://www.w3.org/TR/2007/NOTE-i18n-html-tech-lang-20070412/) 
let us improve language support as suggested by:

 *  [Best Practice 7: Using the body tag]
(http://www.w3.org/TR/2007/NOTE-i18n-html-tech-lang-20070412/#ri20040429.094630704)

 * [Best Practice 8: Handling attribute values and element content in 
different languages]

(http://www.w3.org/TR/2007/NOTE-i18n-html-tech-lang-20070412/#ri20050128.175100333)
 * [Best Practice 12: Deciding on language tag length]
(http://www.w3.org/TR/2007/NOTE-i18n-html-tech-lang-20070412/#ri20030112.224717800)

Because "Best Practice 8" requires adding the `title` attribute in the 
`li` tag, that contains the language name written in the document 
default language, it may be to complicated to handle: for every added 
language the translator will have to translate every name language 
(english, japanese, italian, ecc... ) in the default language document.

A good trade off between "Best Practice 8" and "not annoying 
translators with name language", could be the one used on the top of 
the page at [gnu.org]
(http://www.gnu.org/licenses/license-list.html). Instead of a localized 
value in the `title` attribute of the `li` tag is far more handy 
appending the code language (immutable for all languages) to the 
localized language name.
