xcmCommsStackUpperStackIndex

The value of 'xcmCommsStackIndex' corresponding to a next
higher associated conceptual row in the 'xcmCommsStackTable', or
zero if this stack layer's position is either 'upperMux' or
sometimes 'top' (see usage note below).
              
Usage:  Only for protocol entities whose current purpose is
either 'layerInterWorkingUnit' (ie, relays or gateways) or
'systemInterWorkingUnit' (ie, application gateways), it is
permitted that the stack layer whose current position is 'top'
have an upper layer index pointing to the peer entity (also in a
'top' position) which comprises the 'other half' of a relay or
gateway between two different address domains (ie, an active
protocol conversion relay) - that is the graphed protocol stack
is an inverted 'U'.
