We will provide non-normative guidelines and best practices for multi-tabbed and single-tabbed applications, following the below philosophy and examples:  For a multi-tabbed application: Patient A is opened, Patient B is opened, without closing Patient A, is represented as:  patient-open for Patient A, patient-open for Patient B, no patient-close For a single-tabbed application: Patient A is opened, Patient B is opened is represented as:  patient-open for Patient A, patient-clos_e for Patient A, _patient-open for Patient B Generalized Rule: Apps shall assume that they are integrating with multi-tabbed applications and shall appropriately send *-close events when a context is closed within their system.  The integration may limit the number of tabs supported by app with the user: The user interacting in a single tab app: open A, open B: opening of B closes A. Fundamentally, the user working in a single-tabbed application limits the multi-tabbed application to a single tab.
