To clarify, are you saying that those bare URIs are ambiguous (between
text and the image) until supplied with some disambiguator (eg. an
header in the online case, metadata in the offline case, some other 
formal or informal convention, or the use context)?

If so, I think that's pretty much right.

But I think it also allows Mark to stipulate that
refers to him too: in which case the bare URI is triply ambiguous:
him, the text and the image. The fact that Mark himself isn't
by a GET doesn't strike me as particularly problematic so long as we
that the very act of GET'ing will resolve any ambiguity in the bare URI
a way which is guaranteed to miss Mark and latch onto one of the other
