Yes, identification is the point. I think it might be confusing to have 
a destid *and* a component tag id which are slightly different. The 
destid is unambiguous (if you know whether the device is a switch or 
endpoint) so I think it makes sense to use that if possible.

I still prefer the destid as the single identification id.
