That's correct because the </p> tag _is_ homeless. The <ul> tag 
implicitly closes an open p element that was started by <p>. This 
follows purely from the syntax rules.

Yes, because the error then goes away, syntactically. You then have an 
empty p element, followed by a ul element, followed by an empty p element.

It is correct behavior; the validator correctly reports a syntax error.

Perhaps the validator could issue a _warning_ about an empty p element, 
but that would be complicated (HTML 4.01 prose says that such elements 
should not be used, but I don't think HTML5 has any such statement) - 
and it would need to be separately programmed, which would we difficult, 
I've understood, since the validator is simply based on a generic SGML
