/**

 * Factory for {@link FieldRenderer}.

 *

 * <p>

 * This class can be overridden by a plugin to change the code generation

 * behavior of XJC. Note that such changes aren't composable; for a given

 * schema compilation, only one instance of {@link FieldRendererFactory} is

 * used.

 *

 * <p>

 * See {@link Options#fieldRendererFactory}

 *

 * <p>

 * To be more precise, since {@link FieldRenderer} is just a strategy pattern

 * and by itself is stateless, the "factory methods" don't necessarily need

 * to create new instances of {@link FieldRenderer} --- it can just return

 * a set of pre-created instances.
