For entity references being expanded, the relevant base URI is
provided as argument 3 of the new resolveEntity() call.

What a locator returns is always location of the construct that
triggered the event ... such as an entity reference, or (the case
you're interested in) the entity declaration.

SAX certainly exposes all three distinct locations, which means
that diagnostics can do what you want.  It's just a simple matter
of programming.

All this does go to emphasize that handling of entity expansion
remains one of the more problematic areas of the XML REC.
It wasn't clearly described in the first version, and it's still got
problems in the second edition.
