/**
 * Test cases for transformers used in the EJB3 subsystem.
 * <p>
 * This checks the following features:
 * - basic subsystem testing (i.e. current model version boots successfully)
 * - registered transformers transform model and operations correctly between different API model versions
 * - expressions appearing in XML configurations are correctly rejected if so required
 * - bad attribute values are correctly rejected
