545 For all actions any error return can fallback to kSOSCCGeneralViewError. This is a catch-all until
546 more code is written and specific additional error returns are identified.
547 For kSOSCCViewEnable actions other possible return codes are:
548 kSOSCCViewMember if the operation was successful and the peer has access to the View
549 kSOSCCViewNotMember if the operation was a successful application to a View, yet the peer must be vetted by another peer.
550 kSOSCCViewNotQualified if the device can't support prerequisite security capabilities
551 kSOSCCNoSuchView if the CFStringRef doesn't match one of the known Views
552
553 For kSOSCCViewDisable actions other possible return codes are:
554 kSOSCCViewNotMember for successfully disabling the View
555 kSOSCCNoSuchView if the CFStringRef doesn't match one of the known Views
556
557 For kSOSCCViewQuery actions other possible return codes are:
558 kSOSCCViewMember or kSOSCCDSNotMember for successful querying of the status for a View for this peer
559 kSOSCCNoSuchView if the CFStringRef doesn't match one of the known Views
