  <description value="Using the [FHIR Version Mime Type Parameter](http.html#version-parameter), a server can
   support [multiple versions on the same end-point](versioning.html#mt-version). The only
   way for client to find out what versions a server supports in this fashion is the $versions
   operation. The client invokes the operation with no parameters. and the server returns
   the list of supported versions, along with the default version it will use if no fhirVersion
   parameter is present"/>
