Neither SGML or XML call <p></p> an empty tag Learn the difference  
between a tag and an element. <p></p> is a start tag followed by a  
close tag. It is not a tag.

According to HTML 4.01, it is an SGML application. HTML 4.01, though  
irrelevant in the real world, is the current HTML recommendation.

"proposals"? Which others (apart from the WHATWG/W3C HTML WG one) are  
you referring to? HTML5 still disallows non-empty elements to close  
themselves (like <p/>). It allows empty elements to have a solidus  
present, though that was only after many complained for the sole  
reason of its appearance.
