Unless, of course, you are wanting valid XHTML ... ;)

That depends which spec you're working with if your working with any spec at all.

XHTML requires closed tag pairs for <li></li>, <p></p>, <option></option> etc.

Ack! That was in what year? 1997? That document is at least four versions out of date! Backslashing literal @ characters in Perl strings was optional at one time too! If you go to w3.org and click on "HTML" then on "Recommendations", you will find that such ancient versions are no longer even listed. That's way past deprecated. (HTML 4.01 is deprecated "legacy" HTML; XHTML1.0 is obsolete, but not quite yet (or only very mildly) deprecated; XML1.1 is the current cutting edge.)

But if you're using XHTML, www.w3.org also says:

Documents must be well-formed

Some/many/most (please choose your appropriate level of dogmatism) developers use XHTML.
