You shouldn't modify the description - this wouldn't work in the
unusual situation where there were one of these devices and is a
bad pattern to set in case someone copies this to another device
where it's more likely there could be multiple instances.  It is
much better to provide two descriptions and select the one which
is needed at runtime.
