Can I use div as a direct child of UL?

Question

I'm having this code:

<ul>    <div>    </div> </ul> 

I feel no issue in my browser rendering it. I have read this too somewhere that li should only be used as direct child of ul.

Is this correct? Can't I use div as a direct child of UL? Is there any documentation for the above confusion?

Edit: This link says I can http://css-tricks.com/forums/discussion/11593/divs-inside-uls/p1

Answer 1

No. The only element that may be a child of <ul> is <li>.

HTML 4:

<!ELEMENT UL - - (LI)+                 -- unordered list --> 

(See also how to read a content model definition in a DTD)

HTML 5:

Content model: Zero or more li elements.

Answer 2

For HTML 5 :

http://www.w3.org/TR/html-markup/ul.html

Permitted contents

Zero or more li elements

For HTML 4 :

http://www.w3.org/TR/html401/struct/lists.html#h-10.2

<!ELEMENT UL - - (LI)+ 

EDIT :

I forget the other HTML5 :D (which have the same specification on this than the W3C's one)
