   -- Usage of Fields in Defining Entity Nodes --
   ----------------------------------------------

   --  Four of these fields are defined in Sinfo, since they in are the
   --  base part of the node. The access routines for these fields and
   --  the corresponding set procedures are defined in Sinfo. These fields
   --  are present in all entities. Note that Homonym is also in the base
   --  part of the node, but has access routines that are more properly
   --  part of Einfo, which is why they are defined here.

   -- Usage of Flags in Defining Entity Nodes --
   ---------------------------------------------

   --  All flags are unique, there is no overlaying, so each flag is physically
   --  present in every entity. However, for many of the flags, it only makes
   --  sense for them to be set true for certain subsets of entity kinds. See
   --  the spec of Einfo for further details.

   --  Note: Flag1-Flag3 are absent from this list, since these flag positions
   --  are used for the flags Analyzed, Comes_From_Source, and Error_Posted,
   --  which are common to all nodes, including entity nodes.
