I agree that this is a fuzzy term.

I wonder whether we can make it a bit more precise.

Two conditions seem to be necessary for the mechanism to work:
* The OBO-Client needs to learn the identifier. For some identifiers
that already requires being quite close to the Target.
* The OBO-Client needs to be authorized to perform the
identifier-to-location information resolution step.

I think that the latter aspect is the restrictive part here.
