#   This is a silly exmple showing how Basic could be used to convey a UML diagram.  It is extremely
#unlikely anyone would ever use FHIR to do this.  (XMI isn't *that* unpleasant :>).  However, it shows
#how somewhat esoteric requirements that won't ever be supported by the core FHIR specification can still
#be managed in a conformant manner.
