+XML Entity Declarations for Characters
+
+The character entity sets distributed with DocBook XML are direct
+copies of the official entities located at
+
+  http://www.w3.org/2003/entities/
+
+They are distributed for historical compatibility and user convenience.
+The DocBook Technical Committee no longer attempts to maintain these
+definitions and will periodically update them from the W3C site if and
+as they are updated there.
+
+Please direct all questions or comments about the entities to the
+individuals or working groups who maintain the official sets.
