Adobe may already own the market for electronic documents thanks to PDF, but the company knows that Microsoft has a habit of showing up late to the party and stealing the crown. In turn, Adobe is beta testing a new project it calls 'Mars', which is an answer to Microsoft's new XPS format.

There's no need for a sublicense. The license is made directly with each user of XPS, which is why you include the notice linking users of your implementation with the XPS license.
The only provision for license withdrawl is if you either sue Microsoft over IP related to XPS or if you make some non-comformant implementation and call it XPS. Both of these apply to PDF and a lot of other format standards.

The GPL requires that there can be no possibility of any reciever of the licences product not being able (by law) to run OR distribute the program.
Therefore the possibility that Microsoft might withdraw the availability of the (perpetual only once granted) XPS license in the future breaks the requirements of the GPL.

No, it's not to do with the notice requirement.
XPS is not sublicensable (sp?) AND the patent license can be withdrawn* by Microsoft at any time.
PDF (AFAICS) has no such restriction.
