Form to Schema Crosswalks
The Crosswalks provide a line by line reference of the schema elements, patterns and descriptions. They should be used only as a guide when developing software. Always refer to the actual schema files in the link below when developing software.
XML Schemas, Business Rules and Release Memo
Special attention should be paid to the projected start and end dates for AIR Assurance Testing System (AATS) and Production.
Throughout the year updated versions of these files may be posted. Each version will show the start date and end date for both AATS and Production when that file version should be used. Multiple versions of these documents may be in use at the same time. Included within the schema file is a DIFF File showing differences from the previous version.
