This schema is specified in IEEE 1671-2006, "IEEE Trial-Use Standard for Automatic Test Markup Language (ATML) for Exchanging Automatic Test Equipment and Test Information via XML." This schema is a World Wide Web Consortium (W3C) Extensible Markup Language (XML) binding of the ATML Common component defined in IEEE 1671-2006, "IEEE Trial-Use Standard for Automatic Test Markup Language (ATML) for Exchanging Automatic Test Equipment and Test Information via XML." The purpose of this schema is to provide unique types and attributes for ATML schemas. This schema uses the W3C XML Schema definition language as the encoding. This allows for interoperability and the exchange of ATML component instances between various systems. This schema shall not be modified but may be included in derivative works.
