It is a presentation issue, yes, but I still feel that there may be cases
(fringe cases, certainly!) where an application might rather move the
display to an already-embedded/displayed portion of content referenced by a
URI rather than presenting the content yet again.  

I don't consider this a showstopper, however, just a consequence of
allowing other or no value (thanks to #IMPLIED) into the show attribute.
Interesting, but hardly a large problem.

That is not what I'm referring to at all.  There may well be a
misunderstanding, but XInclude-style embeds are not the subject of my message.
