      Admin Extension Attributes hash. 
      
Example:
This example copies an existing admin extension to a new admin extension. I.e. it simply re-saves the admin extension under a new name.
      ($a = ars_GetAdminExtension($c, "AE-foobar")) ||
	    die $ars_errstr;
      $a->{name} = "Copy of ".$a->{name};
      ars_CreateAdminExtensio($c, $a) || die $ars_errstr;
