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