Note the 'at a glance' above.  The relevant aspect of the WPN proposal
here is that it should be possible to determine certain key things
about a URI _from the URI itself_.

I wasn't aware of an agreed form for triples -- your form looks fine
too.

Precisely.  Our contention is simply that it should be possible to
distinguish _in the relevant URIs themselves_ whether the intended
referent is "in the Web" or "denoted by something in the Web".

That's an empirical question -- we'll find out.
