/**
 * EngineConfigurationFactory is an interface used to construct
 * concrete EngineConfiguration instances.
 * 
 * Each EngineConfigurationFactory must also (directly) implement
 * the following static method:
 *
 *     //Creates and returns a new EngineConfigurationFactory.
 *     //If a factory cannot be created, return 'null'.
 *     //
 *     //The factory may return non-NULL only if:
 *     //  - it knows what to do with the param (check type & process value)
 *     //  - it can find it's configuration information
 *     //
 *     //@see org.apache.axis.configuration.EngineConfigurationFactoryFinder
 * 
 *     public static EngineConfigurationFactory newFactory(Object param);
 *
 * This is checked at runtime and a warning generated for
 * factories found that do NOT implement this.
