JAXP: XSLTC transformer swallows empty namespace declaration which is necessary to undeclare default namespace

Hi Christoph, Joe,
Actually what I see with the latest dev version of
JDK 9 (eng. build built a few minutes ago) is this:
<?xml version="1.0" encoding="UTF-8"?><root xmlns="ns1"
Notice that xmlns="ns1" appears twice in the root element.
So maybe there's more than one bug here :-(

However, the method declaresDefaultNS() of XslElement always returns false and the comment to it says: "This method is now deprecated. The new implemation of this class never declares the default NS". As I didn't find any other class in the hierarchy overwriting this method, I decided to remove it and to cleanup code. Are you ok with that or is it illegal here?
