Export Map Operation and on-the-fly Datum Transformations

I can't find an explicit answer in the REST API docs, but the Export Map operation doc makes it seem like a MapServer service (regardless of the advertised spatial ref ) can return images of any spatial ref I pass in with the imageSR param. Is that true? Are there no limits on this even if the advertised projection and requested imageSR have different datums?

If someone could point be to an explicit part of the documentation that explains this support in detail I'd be a happier camper.
