Good idea, done that way.

Yeah, lack of easy applicability to other cases was the main thing
bothering me about the processing-instruction fix.

BTW, I tried to also use this <phrase> markup inside the template for
<returnvalue>, so we'd only need one font-switching special case not two.
Didn't work though --- apparently templates don't get applied recursively?
Oh well.
