trouble with our e-mail system, so I send it via hotmail ...

Seth,

If somebody writes some document/context x containing
  <web:Describes about="uri1">
    <nsp:foo ID="y" rsource="uri2"/>
  </web:Description>
then anyone can refer to that particular statement via x#y
and make further statements about it.

I think this also implies (but is not equivalent to)
  <web:Statement ID="y">
    <web:subject resource="uri1"/>
    <web:predicate resource="nspuri#foo"/>
    <web:object resource="uri2"/>
  </web:Statement>
If we *assert* a context containing such reified statement then
we should accept that statement as if it were an axiom and then,
I think, both descriptions are equivalent.

Of course, we often want these statements to be anonymous
resources (no ID attribute).
