035/**
036 * <p>
037 * GenericModelClassFactory is a {@link ModelClassFactory} implementation 
038 * which always returns generic types:
039 * </p>
040 * <ul>
041 *      <li>{@link GenericMessage}</li>
042 *      <li>{@link GenericSegment}</li>
043 *      <li>{@link GenericGroup}</li>
044 * </ul> 
045 * 
046 * <p>
047 * This can be used to run HAPI without any structure JARs, as the generic MCF
048 * has no structure dependencies. See the
049 * <a href="http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/HandlingMultipleVersions.html">using multiple versions</a>
050 * example for more information.
051 * </p>
052 * 
053 * <p>
054 * In combination with {@link ParserConfiguration#setAllowUnknownVersions(boolean)}, the GenericModelClassFactory
055 * can be used to parse future versions of HL7 for which HAPI has no support.
056 * </p>
