Meta Language Tag, Meta Tag Languages

In HTML elements, the language attribute specifies the natural language. This post is mostly worried with how to specify the primary language and the base language in HTML documents.

Example of the META Language Tag:

The value of the Content attribute of the META element is the same as the value of the Content-Language header in HTTP; i.e, a comma-separated list of language codes. For example:
<meta http-equiv="content-language" content="en">
<meta http-equiv="content-language" content="en, fr">

Here is a listing of the ISO 639 2 letter language codes...
