1. Suggest that each WAI html page start with some variant of the
version of HTML DTD it is valid to, such as is used on the WAI homepage:

     <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

2. If and when a document becomes xhtml (as on W3 homepage) it needs to
prefix the DOCTYPE declaration by:

     <?xml version="1.0" encoding="UTF-8"?>
     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

with both a public ID and the system URI. [Caution: MSIE5.5 cannot
accept a dtd denoted by http://... .dtd], though it may recognize
it for document delivery. Opera 5.12 can download it that way.
Neither allow ftp://... to get it.]

Some alternative encoding values to "UTF-8" are "UTF-16",
"ISO-10646-UCS-2", or "ISO-10646-UCS-4" that could be used for the
various encodings and transformations of Unicode/ISO/IEC 10646.
See [ISO10646].

All XML applications are expected to support Unicode. Other alternatives 
are acceptable, including "ISO-8859-1", "ISO-8859-2", ... "ISO-8859-9"
for parts of ISO 8859. See [ISO8859]. Also the values "ISO-2022-JP",
"Shift_JIS", or "EUC-JP" can be used for the various Japanese encoded
forms of JIS X-0208-1997. See [JIS].

     [ISO10646] "Information Technology - Universal Multiple-Octet Coded
     Character Set (UCS) - Part 1: Architecture and Basic Multilingual
     Plane", ISO/IEC 10646-1:1993. The current specification also takes
     into consideration the first five amendments to ISO/IEC 10646-1:1993.



     [ISO8859] "Information Processing - 8-bit single-byte coded graphic
     character encodings - Part 1: Latin alphabet No. 1", ISO 8859-1:1987.
     Other suffixes "-2 through -10 and -13 through -16" correspond to
     other character encodings in the family. Order and pay for ISO
     standards, starting from:


     [JIS] "JIS Character Sets"


     [RFC1766] The %ContentType; and %ContentTypes; media types and the
     %Charset; and %Charsets; character encodings are from RFC2045
     "Tags for the Identification of Languages", H. Alvestrand,
     March 1995.


3. Check WAI pages to make sure that lang is present in all the root

     <html lang="en-US">

or generic english:

     <html lang="en">

Modify the lang (and xml:lang) values appropriately for any translations.
Also within those translations when different languages appear, make
sure that the enclosing tag indicate the lang="..." of the enclosed.

For xml documents in addition to lang="..." add xml:lang="..." attributes
to the root element.
