However, a specific Dataflow that uses the DataStructureDefinition may contain only a subset of the possible range of keys that is theoretically possible from the DataStructureDefinition definition (the total range of possibilities is sometimes called the Cartesian product of the dimension values). In addition to this, a DataProvider that is capable of supplying data according to the Dataflow has a ProvisionAgreement, and the DataProvider may also wish to supply constraint information which may further constrain the range of possibilities in order to describe the data that the provider can supply. It may also be useful to describe the content of a data source in terms of the KeySets or CubeRegions contained within it. 59 59 60 -DataStructureDefinition may contain only a subset of the possible range of keys that is theoretically possible from the DataStructureDefinition definition (the total range of possibilities is sometimes called the Cartesian product of the dimension values).

Multiple such DataConstraints may be present for a //ConstrainableArtefact//.
