If you are dealing with pathological cases, such as a URI that changes
what resource it identifies over time, then you have other things to
worry about. For example, if protocol is not followed the the
different representations might not be of the same resource. In that
case the citation would be of a particular representation (not
captured by the duri).

I think if you are going to handle such pathological cases, then
explanation and motivation has to be in the earlier section of the
document, where one would read about scope.
