--  Representation of object references as typed
--  Interoperable Object References.

--  An IOR aggregates the identification of an interface (i.e. a type
--  identifier) and a set of profiles designating an object that supports
--  this interface. An IOR can be converted to a stringified
--  representation by marshalling it according to CDR, and converting
--  the resulting stream element array into a string of hexadecimal digits.
