Yes, I get that about specs. No, i never said I expected to be said in the specs: "And for those elements that can have content, but at one point or another don't have one, we have this name for them: ..."
I was asking you, how do you call those elements not having content, though their definition in the specs is not "empty element".
<p></p> is not what specs mean by an empty element. But how do you call it? You.
And a possible moot point: an element lacking content IT IS what they mean by an empty element. Their further explanation justifies why they chose to make it so: empty, w/o permitting content on it.
