Cool.

I guess this is fine.  We really don't have a hard goal of
making the Python generator as it stands support anything
but C, but I know a folks are deriving their generators for
other languages from it, and this might conceivably make
their lives easier.

I'm not sure why the generator lives in proto instead of
libxcb.  It seems to me like it ought to be moved.

Seems reasonable.  The XML is definitely supposed to be
language-independent. :-)

I've pushed your patches.  

In the future, it would be great if you could submit each
patch as a separate attachment.  That way I don't have to
break them out with a text editor.

Other than that, it looks great!  Thanks much for the
patches, which I've pushed.  I also "fixed" correponding hex
in render.xml and glx.xml (although the latter constitutes a
definite uglification of the description, I'm afraid).
