+
+     For example, if your document's top-level element is Book, and
+     you are using DocBook directly, use the FPI in the DOCTYPE

+                    [...]>
+
+     Or, if you have a higher-level driver file that customizes DocBook,
+     use the FPI in the parameter entity declaration:
+
+     <!ENTITY % DocBookMathMLDTD PUBLIC "-//OASIS//DTD DocBook MathML Module V1.1CR1//EN"
