REQUIRED : They must be included in the DATA set structure and should not have a missing value for any observation. EXPECTED :These variables must be included in the data set; however it is permissible to have missing values. PERMISSIBLE : These variables are not a required part of the domain and they should not be included in the data set structure if the information they were designed to CONTAIN was not collected.
