Yes, what I applied was what you have provided (I believe):
http://lists.ximian.com/pipermail/mono-patches/2008-March/113937.html

For now I'm fighting against other preedit modes (preedit position
and preedit callbacks), so let me think about it later.
It seems that iiimx and/or atokx3 (Japanese commercial IM) has this
kind of issue; it does not change keyboard's shift state, unlike
scim(-anthy).

I've also generated xim.pdf from xim.ps ;-)

Solaris IM implementation detail was also nice to read (it works on top
of IIIMF and hence it does not always apply to my environment though)
http://opensolaris.org/os/project/input-method/documents/SolIM_Impl.pdf

When I solved the puzzle around preedit mode and XVaNestedList, I
will have to come back to these docs. Probably I had better commit
my ongoing changes to ask for review on what would go wrong.
