Included in the 2022v1.0 Schema package are "DIFF" files which identify the difference between the 2021v4.3 Schema package and the 2022v1.0 Schema package. The XML standardization was applied and are available for program planning purposes. These Schemas and Business Rules will not be used in ATS or Production.
