you bring up an interesting point.

It seems to me that using an ID attribute on a property would be a
convenient way of naming the otherwise anonymous node resulting from
reifying the particular statement. At this point I cannot think of a good
reason why we would have restricted this (speaking as the editor of the
spec). It should be noted, though, that using the ID only makes sense if you
are reifying, since otherwise there obviously is no representation for it
(in the triple space).

OK, so let's for a moment think slightly outside the spec: what would be
wrong with writing something like

  <rdf:Description rdf:about="some.url" rdf:bagID="some.bag.id">
    <someProperty rdf:ID="some.id" rdf:resource="some.other.url"/>

If anybody is keeping track, this is one of the things we may want to fix in
the next version... :-)
