How 'Basic' can be used for essoteric resources - in this case, a UML class model (id = "classModel")

<?xml version="1.0" encoding="UTF-8"?>

<!--   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.  --><Basic xmlns="http://hl7.org/fhir">
