Non Latin1 charsets (draft-holtman-http-negotiation-00.txt)

4.2 Accept-Charset

I think last sentence of first paragraph should be written as
"The ISO-8859-1 character set can be assumed to be acceptable
to all user agents.". Rationale: per HTTP/1.1 draft
(section 3.7.1) entity body without explicit charset can be
US-ASCII only or ISO-8859-1. Thus any conforming user agent must
be able to handle ISO-8859-1.

4.6 Alternates

Can media-type contain charset? Is this a valid exmaple?

Alternates: {"TheProject.fr.html" 1.0
      {type "text/html"} {language "fr"}},
    {"TheProject.en.html" 1.0
      {type "text/html"} {language "en"}},
    {"TheProject.ru.html" 1.0
      {type "text/html;charset=iso-8859-5"} {language "ru"}}
    ("/cgi-bin/xlate?koi8-r+TheProject.ru.html" 1.0
      {type "text/html;charset=koi8-r"} language "ru"}}

5.1 Reactive negotiation

If two alternates are differ by charset only, how
specify preferred one?

Thanks
