That's problematic for EntityResolve::resolveEntity; that requires that
ownership of an InputSource be transferred from to the caller from the
callee.

This could be avoided by doing:

virtual const InputSource *
resolveEntity(const char *publicId,
              const char *systemId);

instead of:

virtual void
resolveEntity(const char *publicId,
              const char *systemId,
              InputSource &inputSource);
