The namespace is unchanged.

You need to be aware that XSD 1.1 is still a working draft and subject to
change, and that there are only partial implementations available.
Assertions and some other significant facilities of XSD 1.1 are implemented
in Saxon-SA 9.1. I believe there is also a partial implementation in Xerces,
but you have to work at the level of the nightly builds.
