1) REQUIREMENT

"13.5.1 Language(s) labelling 
There are two types of language labelling: 
 
* Language(s) of the file: the metadata indicating the language(s) in a file. It could be several languages. In the Dublin Core is the label language; also called language of the intended audience. 
 
* Processing language: the language at any given point in the file. It can be only one language. It is particularly important in the case of multilingual files. In XML, normally the attribute xml:lang. Also called text-processing language."

From
 Open architecture for multilingual parallel texts
 http://arxiv.org/pdf/0808.3889v1


2) SYNTAX

 2.1) Language(s) of the file
  2.1.1) One language: meta or HTML attribute
  2.1.2) Several languages: only meta

 2.2) Processing language inheritance
   Scheme ("http", but also from "file")
   meta
   lang attribute in the top HTML element
   lang attributes in the other elements going down.


4) RATIONALE

"The reason for recommending META as opposed to the HTML element with the lang attribute are:

* N-lingual document could be specified. For example, a bilingual French/Spanish document can be specified.

* The language(s) would be transmitted in the Content-Language field of HTTP header."

From
 http://www.w3.org/TR/1998/NOTE-html-lan-19980313

i.e., meta works for all the cases.


5) "INTENDED AUDIENCE" is a confusing term

"This should simply be named 'primary language' of something similar.

'Intended audience' is confusing. For example, if the document is
written in simple French intended for an audience of English speakers
learning French, it must be labelled 'fr' (the language of the
document) and not "en" (the  intended audience).

The meaning is as the 'Language' element in the Dublinc Core: 

 'The language of the intellectual content of the resource.'
