* Schema-to-Java compiler.

*
*
* All the errors found during this process will be sent
* to the registered {@link ErrorListener}.

Tips: namespace URI {@code -> } package customization
*
* The caller can feed the following synthesized schema
* to achive the namespace URI {@code -> } Java package customization:
*
{@code
*
*
*
*
*
* }
* Feed this synthesized schema document for each namespace URI
* you need to map.
