But the whole idea is that the virtual labels and packing are configured
dynamically (by the commissioner) according to their specific needs.
If a model doesn't receive the *value* of the label, you would need a
separate model for each of the virtuals. This is problematic, because
composition data is immutable, so you wouldn't be able to reconfigure
these mappings without at least re-provisioning the whole network.

Aren't *we* the community? :P
