   * The DOMImplementation class is description of a particular
   * implementation of the Document Object Model. As such its data is
   * static, shared by all instances of this implementation.
   * <p/>
   * The DOM API requires that it be a real object rather than static
   * methods. However, there's nothing that says it can't be a singleton,
   * so that's how I've implemented it.
   * <p/>
   * This particular class, along with DocumentImpl, supports the DOM
   * Core, DOM Level 2 optional mofules, and Abstract Schemas (Experimental).
