No. Expat, on its own, will never try to access external
entities. Also, expatreader will always refer to the EntityResolver
for that - although the default entity resolver will arrange to open
the system ID.

Expat *will* report an error if it can determine that there is one
even without reading the external subset - e.g. if the document is
standalone, or if there is no declared external subset. The latter is
what you are observing: with only an internal subset, expat can know
what the available entities are.
