Christian,

If we are making a change here, I propose that we delimit the triples by
parentheses or brackets.  Something like

topologyDescriptor   = TopologyToken LBRKT topologyTriple
                   *(COMMA topologyTriple) RBRKT
topologyTriple = LBRKT terminationA COMMA terminationB COMMA
                  topologyDirection RBRKT

Cheers,

John
