	   element => [
	       [qw/foo bar/] => {
		   type       => 'leaf',
		   value_type => 'string'
	       },
	   ]
	);

	### prints
	# name	       value	    type	 comment

DESCRIPTION

       This module is used directly by Config::Model::Node to describe a node element. This module returns a human readable string that shows the
       content of a configuration node.

       For instance (as shown by "fstab" example:

	name	     value	  type	       comment
	fs_spec      [undef]	  string       mandatory
	fs_vfstype   [undef]	  enum	       choice: auto davfs ext2 ext3 swap proc iso9660 vfat ignore, mandatory
	fs_file      [undef]	  string       mandatory
	fs_freq      0		  boolean
	fs_passno    0		  integer

       This module is also used by the "ll" command of Config::Model::TermUI.

CONSTRUCTOR

   new ( )
       No parameter. The constructor should be used only by Config::Model::Node.
