/**
 * Class JobMessageFromOperator is a printing attribute class, a text attribute, 
 * that provides a message from an operator, system administrator, or 
 * "intelligent" process to indicate to the end user the reasons for 
 * modification or other management action taken on a job. 
 * <P>
 * A Print Job's attribute set includes zero instances or one instance of a 
 * JobMessageFromOperator attribute, not more than one instance. A new 
 * JobMessageFromOperator attribute replaces an existing JobMessageFromOperator 
 * attribute, if any. In other words, JobMessageFromOperator is not intended to 
 * be a history log. If it wishes, the client can detect changes to a Print 
 * Job's JobMessageFromOperator attribute and maintain the client's own history 
 * log of the JobMessageFromOperator attribute values. 
 * <P>
 * <B>IPP Compatibility:</B> The string value gives the IPP name value. The 
 * locale gives the IPP natural language. The category name returned by 
 * <CODE>getName()</CODE> gives the IPP attribute name.
