Abstract

   This document discusses the marking of natural language in HTML
   documents and its relation with HTTP. It should be read together with
   Internationalization of the Hypertext Markup Language [I-HTML].
   
Table of Contents

   {later}
   
Example

   The general look would be:
   
   <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">
   <HTML LANG=fr>
   <HEAD>
   <TITLE>Mon doc français</TITLE>
   <META HTTP-EQUIV="Content-Type" Content="text/html;
   charset=iso-8859-1">
   </HEAD>
   <BODY>
   Je suis un Berlinois.
   </BODY>
   </HTML>
   
Language(s) of a document

   This is defined in a similar way to traditional publication on paper:
   
     Monolingual document
          When the bulk of the document is in one language.
          
     Multilingual document
          When the bulk of the document is not in one language. For
          example, a bilingual French and English document.
          
Behaviour

   <HTML LANG=xx> indicates the language for the whole document with an
   ISO-639 two letter code. This is a declaration that the document is
   monolingual.
   
   The language indicated by the <HTML LANG ...> should be included in
   Content-Language of the HTTP header. If a <META
   HTTP-EQUIV="Content-Language" Content="yy, zz"> is also present in the
   document, the Content-Language should contain the aggregation of the
   language in <HTML LANG ...> and <META HTTP-EQUIV ...>. For example
   (from the fragments above) the Content-Language should contain xx, yy,
   zz.
   
   Multilingual documents should not include the LANG attribute in the
   HTML tag (<HTML LANG ...>.) Languages should be marked with the LANG
   attribute using the appropiate tag; for example, <P LANG=fr>. The
   languages indicated by the other tags should not be included in
   Content-Language. If the author of the document considers that the
   amount of text in other languages is significant, it should indicate
   in the <META HTTP-EQUIV ...>.
   
   <META HTTP-EQUIV ...> does not indicate the language of the document
   or which portion of the document is in which language; this could be
   indicated only by the LANG attribute. It is just an instruction to
   include the language(s) codes in the HTTP header. The document should
   include some portions of the language(s) indicated, but it is not an
   error if no language indicated in <META HTTP-EQUIV ...> is present in
   the document.
   
Maximization

   Servers could use a data structure for maximization purpose so they do
   not have to look each time inside the documents to parse the language.
   This is considered to be part of the document management system and it
   is not discussed in this document.
   
Support

   All this is hot air if it is not supported. Hence, this section will
   list vendors and document producers that support, or intend to
   support, these recommendations.
