<h3>Special Instructions</h3> None.  <H3>Description</H3> <p>The Display Actor requests summary information for a patient whose identifier is not known to the Information Source actor. For example, try Patient ID 555. The Information Source is supposed to respond with an error code of 404.</p>  <H3>Evaluation</H3> <p>For evaluation, the Connectathon monitor will observe the results on the Display Actor. It will probably render a browser error with the error code 404 and nothing IHE specific. The Framework does not require the Display Actor to intercept the error code and format nicely for the user.</p>
