11.3 - Provide information so that users may receive documents according to their preferences

1. Instead of including links such as "Here is the French version of this document", use content negotiation so that the French version is served to clients requesting French versions of documents.
2. In HTML 4.0 most elements allow you to specify the language of the content with the 'lang=" attribute.
3. If it is not possible to use content negotiation, in HTML use 'hreflang' with the <A> or <LINK> elements to identify the language of the target documents.

See the W3C Internationalization document on HTTP Content Negotiation for more information.
