The java.name.class.prefix option spacifies a prefix for a class name for Relaxer objects.
The java.name.class.prefix option takes a prefix name as a parameter.
The java.name.class.prefix option generates no additional classes.
The java.name.class.prefix option adds no additional methods to Relaxer objects.
The string specified by as a parameter for the java.name.class.prefix option is used for a prefix for class names for Relaxer objects.
List 7.28.3.1[javaNameClassPrefix.rng] is a sample schema for the java.name.class.prefix option.

Execution of the Relaxer with the java.name.class.prefix option is as follows:
$ relaxer -java -java.name.class.prefix:X javaNameClassPrefix.rng
Because the Java generator is a default generator, execution of Relaxer as shown below has the same effect:
$ relaxer -java.name.class.prefix:X javaNameClassPrefix.rng
As a result, Relaxer generates six files:
