 * A module defines a set of extensions. There's at least a core module containing classes from the core specification.
 * Then there could be modules for different kinds of use cases, each combining multiple extensions, e.g. a BOSH module, an IoT module, a File Transfer module, etc.
 * 
 * Modules are loaded by the core using the {@link java.util.ServiceLoader} API.
