The first two have been fixed, but the last two validate perfecty when done as XHTML with the validator at http://validator.w3.org/. If the new validator cannot handle XHTML then I'm going to ignore any errors that it spits out.
That being said, there might be bugs in the new validator (as in any piece of complex software).
I am not a nu validation fan (for example in its treatment of XHTMl served as html), I am only using it as a tool to detect some errors, mainly table errors raised by an inconsistency between the column count established by col and colgroup elements and the contents of some rows. In my experience it works well detecting that errors.
