Someone would have to try it, but you can define variables. So it
might be possible to do something like :
circuit=pick-first-value(concatenate(agent.ciruit-id,
agent.remote-id), agent.ciruit-id, agent.remote-id)
host ...
host-identifier circuit "foo"
...
The pick-first-value bit allows for one or other element being null.
IIRC, if you just concatenate two strings, if one of them is null
then the result is null.
