If you will decide for option B, then please do it for all elements that are declared as non-EMPTY. <tag></tag> will be valid for all non-EMPTY elements in both HTML and XHTML. Now given that <div/> might not actually be permitted in xhtml (though > I'm still not 100% convinced) If you find any information that I might be wrong, then please tell me. Because it is not very logical to me too. I prefer to be wrong in this case. option c) could be better alternative to > b), though I'd still insisted on doing it by default.

That's because IE considers the DIV end tag optional, while in fact it is required.
