XML supports two kinds of external identifiers and I think that an
interface that supports them both is actually simpler than one that does
not -- in the sense that it mirrors the language structure better. If we
leave publid identifiers out, then users must guess at our reason for
doing so. Being different from XML is non-intuitive.

We could replace "getCurrentEntity()" with "getCurrentLocation(Entity
entity, int linenum, int colnum, int offset)" and kill two birds with
one stone.
