That brings the list of vendors that have correctly implemented MSTP
to zero, as far as I'm aware.  Any VLAN ID, regardless of it's status
on the switch or internal status, must be able to be mapped to an
instance.  Especially since that entails nothing beyond setting a bit
in a data structure that gets hashed...

The good news is that they should be convinced fairly easily - tell
them to look at IOS, it correctly permits any dot1Q ID to be mapped.
I had to argue with HP for three years before they removed the
requirement that the VLAN exist.  They had lost our business by then.
