/**
 * A test class for SchemaManager load() method. We test those methods here :

 *     boolean loadDisabled( Schema... schemas ) throws Exception
 *     boolean loadDisabled( String... schemas ) throws Exception

 *     boolean loadRelaxed( String... schemas ) throws Exception
 *     boolean loadAllEnabledRelaxed() throws Exception
