This schema is specified in IEEE Std 1671.2-2008, "IEEE Trial-Use Standard for Automatic Test Markup Language (ATML) for Exchanging Automatic Test Equipment and Test Information via XML:Exchanging Instrument Descriptions." This schema is a World Wide Web Consortium (W3C) Extensible Markup Language (XML) binding of the ATML Instrument Instance component defined in IEEE Std 1671.2-2008,"IEEE Trial-Use Standard for Automatic Test Markup Language (ATML) for Exchanging Automatic Test Equipment and Test Information via XML:Exchanging Instrument Descriptions." The purpose of this schema is to allow the creation of IEEE Std 1671.2-2008 Instrument Instance instance documents. 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.
