+  The ensemble-id is an identifier specified by the USER that uniquely refers to an SDC PARTICIPANT ENSEMBLE.
+  To clarify which pm:EnsembleContextStates are needed, three examples are given.
+
+  Example 1: treatment session
+    The fact that a POC MEDICAL DEVICE is currently working in a (temporal) logical group based on a treatment session
+    may be expressed by a pm:EnsembleContextDescriptor. If each of its pm:EnsembleContextStates describes a step in
+    this treatment session, then the manipulation returns only the state handle of the pm:EnsembleContextState with
+    @ContextAssociation = 'Assoc' that indicates membership in the logical group resp. SDC PARTICIPANT ENSEMBLE. The
+    provided ensemble-id refers to this logical group resp. SDC PARTICIPANT ENSEMBLE. In this scenario there shall be
+    only one pm:EnsembleContextState with @ContextAssociation = 'Assoc' at a time for the pm:EnsembleContextDescriptor.
+
+  Example 2: location inferring
+    If a pm:EnsembleContextDescriptor has multiple pm:EnsembleContextStates whereby each describes a membership of a
+    location-inferred SDC PARTICIPANT ENSEMBLE if associated. The manipulation shall return the state handle of the
+    pm:EnsembleContextState with @ContextAssociation = 'Assoc' that indicates membership in the SDC PARTICIPANT
+    ENSEMBLE referred by the provided ensemble-id.
+
+  Example 3: general hospital process
+    Consider a general process within the hospital with multiple steps whereby each step is divided into multiple minor
+    steps describing the major step more precisely. Membership of this main process as well as of the sub processes is
+    modeled by a pm:EnsembleContextDescriptor that has multiple pm:EnsembleContextStates for the major as well as for
+    the minor steps. To indicate membership in a sub process referred by the provided ensemble-id a
+    pm:EnsembleContextState representing a major step and a pm:EnsembleContextState representing a major's minor step
+    have to be associated. The manipulation shall return the state handles of both pm:EnsembleContextStates.
+
+  The state shall be persistent until a next manipulation call. If the device is not able to maintain the static state,
+  it shall return RESULT_NOT_SUPPORTED.
