! 
! 	Version	   Date	     Who	Description
! 	-------	-----------  ---	-----------
! 
! 	  1.1	31-May-1983  CGN	Added crm$w_ref_length and
! 					crm$a_reference to support the new
! 					CDD$K_REC_REFERENCE attribute.
! 
! 					Added crx$b_description_cnt and
! 					crx$a_description to support root
! 					descriptions.
! 
! 					Added crm$v_string_type and
! 					crm$v_compute_type.
! 
! 					Added crm$w_max_digits.
! 
! 					Added crm$v_debug_flag to help
! 					interpret debugging dumps.
! 
! 					Added crm$v_first_child.
! 
! 					Added cro$l_max_length,
! 					cro$l_max_member_length, cro$l_min_offset,
! 					and cro$l_min_member_offset
! 
! 	  1.2	14-Mar-1984  CGN	Added crm$v_blank_when_zero to support
! 					CDD$K_REC_BLANK_WHEN_ZERO.
! 
! 					Added crm$v_right_justified to support
! 					CDD$K_REC_RIGHT_JUSTIFIED.
! 
! 					Added crm$w_initial_length and
! 					crm$a_initial_value to support
! 					CDD$K_REC_INITIAL_VALUE.
! 
! 					Added crm$v_source_type_trunc,
! 					crm$v_reference_trunc, crm$v_initial_value_trunc,
! 					and crs$v_string_trunc to flag truncated
! 					strings.
! 
! 					Added crm$v_facility_use_1 to 6 to
! 					allow client facilities to mark nodes
! 					for their own purposes.
! 
! 					Added cro$w_tag_val_cnt, cro$a_tag_values,
! 					and the new crx_literal_list node to support
! 					support CDD$K_TAG_VALUES.  (crx_literal_list
! 					nodes support literal value sets in
! 					general, but tag values are the only
! 					use currently).
! 
! 					Add crs$v_binary_string to distinguish
! 					binary strings from text strings.
! 
! 					Delete all references to CDD$K_REC_LITERALS,
! 					since the attribute has been removed
! 					from the protocol documentation and it
! 					looks like nobody will ever support or
! 					use it.
! 					
! 	  1.3	23-Mar-1984  CGN	Added cro$l_total_length.
! 					
!	4	4-June-85	CLR	Use facility-use-bit 3 to flag
!					fullword-allocated initial values.
!
! 
!  The general form of the record description returned by the record.
!  extractor is that of an acyclic graph.  The root node is crx_record,
!  which points to the crx_member node for the first member of the record.
!  All record members at the same logical level are linked as siblings,
!  and crx_member points to the crx_member node for it's first subfield,
!  if any.
! 
!  The crx_dimension, crx_overlay, and crx_stringlist nodes are
!  optional subgraphs of crx_members which have those attributes.
! 
!  All facility-specific information is isolated in optional facility-specific
!  nodes.  These nodes are pointed to by the nodes for which facility-specific
!  attributes are present.  Facility-specific information for only one facility
!  at a time may be present in the record description tree.  
!  As new facilities are supported by the record extractor,  new 
!  facility-specific nodes will be defined.  Likewise, as additional
!  facility-specific information is defined for supported facilities,
!  the facility-specific nodes will be enhanced.
! 
!  All non-facility-specific information contained by a cdd record description
!  is returned.  Not all of it is necessarily interesting.  The protocol and
!  core_level field, for example, will always be the same (otherwise the record
!  description would not have been extracted);  they are returned for
!  completeness.
! 
!  Each field is either "required" or "optional", and either "core" or
!  "non-core".
! 
!  A "required" field is one which will always contain a value in any
!  occurence of it's containing node type; a language processor
!  does not have to consider the case of that attribute being
!  undefined or absent.  An "optional" field is one which might not contain
!  a value;  a language processor must consider the case of that attribute
!  being undefined or absent.  By convention, a numeric field that contains
!  no value is zero; a character field that contains no value is blank.
!  For those fields (e.g. lower_bound) for which zero is a valid value, a flag
!  is defined to differentiate a zero value from a non-value.
! 
!  A "core" field is one whose value must not be ignored by a language
!  processor if it contains a value.  A non-core field is one which may be
!  ignored if a language processor does not wish to process it.
! 
!  A field which is neither "core" nor "non-core" is not a cdd attribute;
!  such a field is provided to aid in processing of the "core" and "non-core"
!  fields.
! 
!  For more information, see "VAX-11 Common Data Dictionary Protocol for
!  Storing Record Descriptions".
