+; VITAL concerns:
+;
+; The library ieee contains (among other packages) the packages of the
+; VITAL 2000 standard. When a design uses VITAL 2000 exclusively, it should use
+; the physical library ieee (recommended), or use the physical library
+; vital2000, but not both. The design can use logical library ieee and/or
+; vital2000 as long as each of these maps to the same physical library, either
+; ieee or vital2000.
+;
+; A design using the 1995 version of the VITAL packages, whether or not
+; it also uses the 2000 version of the VITAL packages, must have logical library
+; name ieee mapped to physical library vital1995. (A design cannot use library
+; vital1995 directly because some packages in this library use logical name ieee
+; when referring to the other packages in the library.) The design source
+; should use logical name ieee when referring to any packages there except the
+; VITAL 2000 packages. Any VITAL 2000 present in the design must use logical
+; name vital2000 (mapped to physical library vital2000) to refer to those
+; packages.
+; ieee = $MODEL_TECH/../vital1995
+;
+; For compatiblity with previous releases, logical library name vital2000 maps
+; to library vital2000 (a different library than library ieee, containing the
+; same packages).
+; A design should not reference VITAL from both the ieee library and the
+; vital2000 library because the vital packages are effectively different.
+; A design that references both the ieee and vital2000 libraries must have
+; both logical names ieee and vital2000 mapped to the same library, either of
+; these:
