please excuse me for this silly commit. XMLSchemaValidator was refactored sometime ago for improved maintenance efforts. significant code from it was moved to a new class whose child class is XMLSchemaValidator. I'm rementioning the contributors for the new class. I've removed my name for authorship of this component, since I was not a primary contributor to this.
