description: 'This acts as an overall ''required'' binding for an element that already has a less restrictive binding. It is used when there is a desire to have a ''small'' enumerable binding that meets most needs and where the overall value set that the codes must be drawn from is ''infinite''. The the base less restrictive binding SHALL be a proper subset of the max binding valueset. In most cases, this extension is used where the base binding is ''extensible''.
