Constraint Schema

This is a NIEM schema that adds additional constraints and restrictions to components.A constraint schema was used in the 2008 version of the standard to add cardinalityconstraints to schemas that were automatically generated by a NIEM tool called SSGT(Subset Schema Generator Tool). The tool has been updated to directly specifycardinality constraints in the NIEM subset schema, so constraint schemas are no longerprovided. However, an implementer is permitted to define their own constraint schemato add further restrictions to the standard. An example is to only allow certain recordtypes in a transaction.
