It's not easy to send xml:lang that always provides accurate 
information. Yes, we can guess the language by looking at system locale, 
client's translation pack selected by user, active keyboard layout, etc, 
etc, but it still won't work automatically in all cases.

If I talk with one person in English and with other in Russian, a client 
could detect that different keyboard layouts and send different xml:lang 
attribute automatically. But if I talk in English and Polish, and all 
English characters are included in Polish layout, then the only way to 
detect this (without using AI, etc), would be asking the user to 
manually specify the language. And now think how many users will always 
set conversation language in every chat window..
