In your example, there is nothing configured as far as I can tell.

The way the interfaces data model supports pre-configuration is by having a
_name binding_; a pre-configured interface is applied once the name of the
pre-configured interfaces matches the name of a
(physical) interface. I think Martin is asking the question whether the same
model of using name bindings can be applied in your case and if not why not.

[Bart Bogaert] I'm afraid I am lost in the names being used here.  Whether
it's called name binding or pre-configuration or still something else, the
key point is that we configure objects in the device prior to them being
physically present, nothing more, nothing less.  The consequence of this
being that these objects should be present in the data tree of the device
and once the HW gets plugged all operational data linked to that comes into
existence too.  I do not know of another way to explain what is intended
with what we call 'pre-configuration'.
