<H3>Special Instructions</H3> This test is designed to be run in parallel with XDS_Provide_and_Register. Use the Kudu tool to run XDS_Provide_and_Register with a Document Source and Document Repository. Assuming you have enlisted a Document Registry to run that test, use the Kudu tool to start/stop that test. Ask the Connectathon monitor to evaluate both tests at the same time.  <H3>Description</H3> The XDS_Register_Document test is a test of ITI transaction 14. A Document Source supplies at least one document and submits it to a Document Repository. The Document Repository then registers that document with the Document Registry participating in this test. <p> To run this test, locate a Document Source that can cooperate and provide a document. Have that source provide the document to the Document Repository; the Document Repository then registers the document with a Document Registry.</p>  <p>When this test has been completed, log the following information in the <i>Comments</i> section: <ul> <li>Patient ID </li> <li>XDSSubmissionSet.uniqueId</li> </ul>  <H3>Evaluation</H3> The Connectathon monitor can observe the log or database information in the Document Registry or enlist the help of a Document Consumer to query the Document Registry and retrieve the document.  <p>Note that the transaction ITI-14 between the Registry and the Repository is optional when the actors are combined.</p>  <p>The monitor can optionally use a NIST evaluation tool to examine the contents of the Document Registry</p>
