  <comment value="This operation is a constrained version of the IHE PIXm (Patient Identifier Cross-Reference for Mobile).  It returns business identifiers that correspond to the same patient as a specified source identifier.  The operation can be invoked by GET, passing the parameters as part of the URL or by transmitting a [Parameters](pcr-parameters-pixm-in.html) instance in the HTTP body.
