It should validate. According to the w3c compatibility guidelines
(http://www.w3.org/TR/xhtml1/guidelines.html):

C.2. Empty Elements

Include a space before the trailing / and > of empty elements,
e.g. <br />, <hr /> and <img src="karen.jpg" alt="Karen" />. 
Also, use the minimized tag syntax for empty elements, e.g. <br />, 
as the alternative syntax <br></br> allowed by XML gives uncertain 
results in many existing user agents.

C.3. Element Minimization and Empty Element Content

Given an empty instance of an element whose content model is not EMPTY
(for example, an empty title or paragraph) do not use the minimized 
form (e.g. use <p> </p> and not <p />).

fair enough.
