Charges

The charges extension is used to record details of the total charges that are estimated or applied to users or government during the operation of a Public Private Partnership contract.

This can be used to provide a breakdown of government support to a project, on a period-by-period basis.

The charges extension introduces a charges array to the contracts.implementation object.
