Should Representation be confined to the Business Layer

Currently Representation is confined to manifesting a Business Object, but I suggest it might be useful to extend this to any form of Passive Structure, even perhaps add it to the Core Metamodel.

For example a 'Parking Ticket' (Penalty Notice) is as much a Representation of a Data Object or an Artifact as it is a Business Object. Currently to show this I would have to create a Business Object and have a Data Object realize it.
