Fair enough.  That seemed to me like a roundabout way of coming at the problem, but it sounds like the simplest fix.

It might be helpful, even in this case.  We expect the options to go unhandled for MOAB native file types.  But if the options go unhandled for a different file type, that's unexpected, and it would be polite to issue a warning to the user.  It's still a cosmetic issue, though, and probably does not merit an interface change.

Thanks for your help.
