Theoretically Silverlight is supposed to use Microsoft's UIAutomation for
accessibility. I do not know that JAWS has any specific UIAutomation
functions? My impression is it mostly is mapping back to MSAA functions.
At any rate the best bet would be to see what information is available via
MSAA/UIAutomation using Microsoft Object Inspect or UISpy.
That said, I've not came across an accessible Silverlight app or one that
seemed to expose enough to be useful.

Subject: [jawsscripts] HTML DOM with microsoft silverlight
Out of curiousity, has anyone successfully engaged with Silverlight? I tried
with the following code to get some information out of Silverlight. The
following code also gives you access to the XMLDom which I used for one Note
and the shell for windows to get the objects on a webpage:
I did notice that Silverlight only lets Javascript to get access to the
object so I am just figuring that JAWS script isn't going to be able to get
anything from the Netflix Silverlight player. Any thoughts?
