Well, my point is that it certainly won't have any schema type unless we
write something in our specification to make it so.

Furthermore, I'm quite nervous about this direction.  A .gif file is surely
not conformant with the lexical representation of a schema binary;  even if
we wished to associate the two, we would have to write a spec saying how.
If I point to an ASCII text file, does that turn into binary?  string?
string with character repertoire restricted by regex to ascii only? binary
for the encoded characters?

This all feels like a very slippery slope to me, hence my suggestion that
we allow such nodes to be untyped (they are obviously NOT of the schema
anytype, since they need not  conform to any of the limitations for XML
character sets or other restrictions that characterize XML simple and
complex types.)
