38   * GenericModelClassFactory is a {@link ModelClassFactory} implementation 
39   * which always returns generic types:
40   * </p>
41   * <ul>
42   * 	<li>{@link GenericMessage}</li>
43   * 	<li>{@link GenericSegment}</li>
44   * 	<li>{@link GenericGroup}</li>
45   * </ul> 
46   * 
47   * <p>
48   * This can be used to run HAPI without any structure JARs, as the generic MCF
49   * has no structure dependencies. See the
50   * <a href="http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/HandlingMultipleVersions.html">using multiple versions</a>
51   * example for more information.
52   * </p>
53   * 
54   * <p>
55   * In combination with {@link ParserConfiguration#setAllowUnknownVersions(boolean)}, the GenericModelClassFactory
56   * can be used to parse future versions of HL7 for which HAPI has no support.
57   * </p>
