I think there are two differences (a) there is an indirection: the binding of the prefix to the URI can be changed at any time, in one place (b) there is a convenience; the syntactic notation of prefix:local-name is familiar and people are comfortable with it. > > there should be _no_ formal difference in terms of expressiveness > between binding an iri to a prefix and binding an iri to a variable. > I agree with that. We aren't talking about expressive power here, we are talking about usability considerations. Michael Kay
