/**
 * Class {@code RequestingUserName} is a printing attribute class, a text
 * attribute, that specifies the name of the end user that submitted the print
 * job. A requesting user name is an arbitrary string defined by the client. The
 * printer does not put the client-specified {@code RequestingUserName}
 * attribute into the Print Job's attribute set; rather, the printer puts in a
 * {@link JobOriginatingUserName JobOriginatingUserName} attribute. This means
 * that services which support specifying a username with this attribute should
 * also report a {@code JobOriginatingUserName} in the job's attribute set. Note
 * that many print services may have a way to independently authenticate the
 * user name, and so may state support for a requesting user name, but in
 * practice will then report the user name authenticated by the service rather
 * than that specified via this attribute.
 * 
 * IPP Compatibility: The string value gives the IPP name value. The
 * locale gives the IPP natural language. The category name returned by
 * {@code getName()} gives the IPP attribute name.
