8-) Sorry Stuart, I was referring to the database/merging example.  I
thought that explained the problem with ambiguity very well.

I figured as much, and was happy with the revised text in that respect.

True.  So if you point was to suggest that the conference registration
form, by virtue of asking for a registrant's "email address" rather
than their "globally unique identifier", defines the context for
interpretation, I'd agree.  I just didn't see the example explaining
that point.  If it can be fixed, then great, though as I mentioned to
Walden, I'm not sure it can while remaining succinct.

My apologies for the number of exchanges required to get to this
