How about something like "callers" or > "transfer" ?
`owned' applied to a parameter means that the parameter owns the object, that is, the ownership of the object is transferred in the same direction as the parameter value: to the callee for input paramters, to the caller for output parameters, and input to the callee and output to the caller for `ref' parameters. The issue with the caller/callee owned terminology is that this does not apply very well to `ref' parameters and fields, which means that we would need yet another modifier in those places.
