+The following changes have been made (with the permission of the
+W3C MathML Committee), to this DTD:
+
+1) %product.class; is defined below and also defined in 
+JATS-default-classes.ent. Renamed class in the MathML DTD
+until JATS names can be changed. Renamed the parameter entity
+to "mml-product.class".
+
+2) The parameter entity named "name" was commented out. It is never
+used in the MathML 3.0 DTD, and its presence causes processing
+errors in the Mulberry Tag Library software.
+
+3) id CDATA #IMPLIED ==> id ID #implied
