I think it's also fine to give the app control over when the parser
performs the expansion.  One reason to do this is that the internal
entity may be defined in an external parameter entity or external DTD
subset.  An app may not want to wait to retrieve this when it could be
continuing to parse the entity in which the reference occurs.
