Underline element.

Hi all :)

I was reading the HTML 5 draft and something is strange about <u> tag.
In HTML 4, <u> tag is depreciated [1], and <u> tag doesn't exist in HTML 
5 [2]. I don't find anymore informations about it in XHTML 1.0 or 1.1. 
So I deduce that we can't underlined an element in HTML right now ?

Best regards,
-Ivan
