Yes, because <p> is NOT a separator, it's a container.  Instead of
paragraph<p>paragraph, it's <p>paragraph</p><p>paragraph</p>.

Your brain is easily drained, I guess. :)

This has actually been a requirement all the way back to HTML1; it's
just that browsers have tended to be forgiving about it.
As to what it means, it means that tags have to be closed in the
inverse order they were opened.  So, for instance, if you use those
old nasty presentation tags <b> for bold face and <i> for italic,
you have to make something both bold and italic <b><i>like this</i></b>,
not <b><i>like this</b></i>.

Actually, the <table> border attribute takes a numeric value specifying
the width of the border.
