NOTE to developer: This is only a sample resource. For the resource structure and valusets always refer the section "Overview" under each profile definition in the Implementation guide. If an element is defined as an array (0..*) in the standard and in RDC profile as an object (0..1), please note that it should still carry the structure of an array with one occurance.
