Hi Piotr,

SID_AccessibilityUnk is used to get the wrapped IAccessible out of the
Dynamic Annotation wrapper. This ends up being useful due to the fact
that the IAccessible wrapper doesn't pass QI calls to the IAccessible it
wraps, which means things like IOleWindow don't get passed through.

The diff you've attached looks good. Is it good for you? Would you like
more tests around this?

Thanks,
Connor.
