XMLNS for russian site

Hello, I have russian site (domain zone is .ru).  I read the article
about this XHTML 1.0
Transitionalhttp://www.w3.org/QA/2002/04/valid-dtd-list.html

What would be the correct Doctype for my site?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="ru" lang="ru">
This correctly?
Thanks.
