I see. I didn't want to propose that the Infoset be reflected in RDF.
I think Tim expressed some concerns against that. I just proposed that
the Infoset be used as the most appropriate denotation of XML Literals,
without any implications for implementations. It seems to me that
the Infoset is the most appropriate denotation for XML Literals because
it is a well-defined spec, it captures the 'nature' of XML, and it is
definitely better suited for the job that a sequence of octets or
a sequence of characters. The later, in my view, would be similar to
saying that an integer denotes a sequence of digits (not starting
with a zero), or that it denotes a sequence of octets in (packed)
BCD notation. These seem appropriate when looking into actual
representations on a machine, but not when talking about denotations.

Anyway, if you find a solution that avoids the later but doesn't
explicitly mention the Infoset, that's okay by me, too.

Regards,    Martin.
