A note on JAXP
-----------------------

Since Java 1.4, JAXP (Java API for XML Processing) is part of the 
JRE/JDK. Every JVM includes the APIs and an implementation. However, 
older JREs often contain implementations with bugs that are triggered 
by code in Apache FOP and therefore need to be overridden. Now, since 
JAXP is part of the class library, special precautions are necessary 
to replace the original implementations. This is not done by simply 
adding new JARs to the classpath as these classes would never be 
loaded (due to Java's class loader hierarchy). 

Replacing the default implementations involves understanding the 
"Endorsed Standards Override Mechanism".
More information can be found here:
http://java.sun.com/j2se/1.4.2/docs/guide/standards/index.html

See also:
http://xml.apache.org/xalan-j/faq.html#faq-N100EF

Essentially, you have two different possibilities:
- add the replacement JARs in the jre/lib/endorsed directory of your JRE.
- Use the -Xbootclasspath/p: option when starting the JVM (may not be
  available for every JVM).
