032/**
033 * Specialized version of ModelClassFactory that always returns the same version. This is useful when designing
034 * applications which are expected to handle multiple versions of HL7. The recommended approach is to
035 * configure this factory to handle the newest version of HL7 you intend to support. Since HL7 is a backwards
036 * compatible protocol, older versions should always be able to parse correctly into a newer message structure.  
037 *
