What Is a Standard?

The answer to this question depends on what the standard is supposed to do. In the case of terminology, it might be a format catalog and a data set. In the case of an XML-based standard, it might be metadata that describes the SAS representation of the XML. It might be data sets that control validating the SAS representation of the XML. It might be routines to convert the SAS representation to the actual XML files. Or, it might be initialization files for standard-specific properties.
The minimum number of items that are needed to register a standard to the framework are the data sets that define the standard, as well as the standard's SASReferences data set. The macro to register a standard is described in Registering a New Version of a Standard.
