If the code is in italics, this indicates Usage note: every effort has been made to ensure that the code is examples are correct and useful, but they are not selectable ('Abstract') Display The display (used in the display element of a Coding ). If there is no display, implementers should not simply display the code, but map the concept into their application Definition An explanation of the meaning normative part of the concept Comments Additional notes about how to use the code specification.
