/**
 * <!-- begin-user-doc -->
 * An implementation of the commonj.sdo.internal model factory.
 * This model is generated from sdoInternal.xsd, in the tuscany-sdo-impl project.
 * Until the SDO code generator supports regen/merge, follow the following steps to regenerate this model:
 *   1. Regenerate the model into a temporary directory:
 *         XSD2JavaGenerator -generateBuiltIn http://www.apache.org/tuscany/commonj.sdo.internal -targetDirectory <temp-dir> -javaPackage org.apache.tuscany.sdo.model.internal <tuscany-sdo-impl-dir>/src/main/resources/xml/sdoInternal.xsd
 *   2. Delete all the createXXXFromString() and convertXXXToString() methods in the newly generated InternalFactoryImpl and
 *      replace them with the ones from this file (resolve any missing imports).
 *   3. Comment out all simple depedencies (SDOUtil.registerStaticTypes calls) in the init() method.
 *   4. Make sure the top of each generated file contains the ASF License.      
 *   5. Move this JavaDoc comment into the newly generated ModelFactoryImpl class.
