+              for the above restriction)
+
+                - "Family name" and "Given name" must be supported.
+                    - All sync adapters must support structured name. "display name only" is not
+                      supported.
+                      -> Supporting this would require relatively large changes to
+                         the contact editor.
+
+                - Fields are decided from the attributes:
+                    StructuredName.DISPLAY_NAME         if supportsDisplayName == true
+                    StructuredName.PREFIX               if supportsPrefix == true
