Since there's demand for this, I'll make sure the SAX namespace and
namespace-prefix features work correctly on the next release.
Currently they can be set and cleared but don't change anything.

I'd be interested in knowing why these particular ones were important.
I understand the issue with script and style.

Thanks; I'll add that to the to-do list for 0.9.2.  (I forgot to test
for parser reusability; my tests always instantiate a new one.)

TagSoup's content models are implicitly of the form (A|B|C|...)*, so
it thinks the content model of the html element is (head|body)*.
I may do some special-casery to fix this, but probably not for 0.9.2
unless I see a very easy way to do it.

Arise, you prisoners of Windows / Arise, you slaves of Redmond, Wash,
The day and hour soon are coming / When all the IT folks say "Gosh!"
It isn't from a clever lawsuit / That Windowsland will finally fall,
But thousands writing open source code / Like mice who nibble through a wall.
