It would be a completely distinct namespace.

No connection.

1.1 would use the same namespace URI (i.e. using 1999 rather than 2000),
except in the unlikely event that there were changes so drastic that
XSLT 1.0 processors would be able to do nothing useful with 1.1
stylesheets.

The W3C seems to believe that it assists them in the long term
management of the www.w3.org site. It is the W3C not the XSL WG that is
responsible for the choice of namespace URI. My personal opinion is that
it's rather confusing.

It appears to be W3C policy for W3C namespace URIs to include at least a
year.
