You are quite right, provided you keep firmly in mind the distinction
between *being* an internal or external entity, and being
internally or externally *declared*.
Internal entities are those whose replacement text appears in the
declaration, and external entities are those whose replacement text
is referenced by a URI or Publicid. Either kind can be declared
either internally (in the internal subset) or externally (in the
external subset or in an external parameter entity).
It's the first property (*being* an external entity) that is forbidden
in references from attribute values. External parsed entities can only
be referenced from content.
