The zip file contains 1. SubsetSample.xml: This is an XML file that validates against the version 1.87 XSD. The XML file represents a subset of the database. It has information of 5 agencies and has a subset of the Geographic Area Definitions. The XML file was generated mostly using real data but synthetic data was inserted wherever real data was missing. 2. AIRSv1.87.xsd The XSD used to validate the XML. If you are going to validate the XML, please make sure to set the xsi:noNamespaceSchemaLocation attribute of the Source element to the XSD. The XML files have been validated using XMLSPY v2004 rel. 4 . The primary goal of generating the XML was to provide a sample XML instance to test functionality of uploading to the central database and was not to test conformance of vendor systems with the AIRS standard. A smaller subset is provided for easier preliminary testing. Known Issues: The Taxonomy element has an attribute by the name ID and type xs:String. Some validators enforce the uniqueness constraint for any attribute by the name "ID". Therefore, some validators will report the XML instance provided to be invalid due to violation of the unique ID constraint.
