xmlspec: list within a paragraph

Hi spec producers,

The xmlspec DTD allows <ulist> within <p>, but it then produces a <ul>
within a <p>, which is invalid HTML.  
Which is wrong, the stylesheet or the DTD?


And while I'm at it: saxon (6 and 8) inserts an xmlns attribute with
the latest html4 stylesheet, making the output invalid html. xsltproc
doesn't insert xmlns. Which is wrong?

Max.
