Specifying this function will cause the data normally read for this element to be processed using the representation of the structure from which this element inherits. Used this to handle mapping of embedded data of a different representation.

You may use this function in multiple map elements in order to read multiple files. You may not however nest the use of this function. In other words, if a map element contains an I/O expression, no subordinate map element may contain an I/O expression. See the discussion on Input/Output for further details.
