I can't get the xincludes to work.

a) Manual <xi:include href="..."/> fails because
   the path is interpreted relative to the BoostBook
   file which is somewhere in the build directories.
b) [xinclude ...] fails because xinclude is
   a block level element, and this is a phrase
   template.

I think I can fix this, but it's going to
mean quickbook changes.

Even if we were only generating HTML,
I still want the PNG as a fallback.

It should get stripped out automatically,
since the processing of mediaobject is
designed to pick one element.
