  /**
   * A generic grammar for use in validating XML documents. The Grammar
   * object stores the validation information in a compiled form. Specific
   * subclasses extend this class and "populate" the grammar by compiling
   * the specific syntax (DTD, Schema, etc) into the data structures used
   * by this object.
   * <p>
   * <strong>Note:</strong> The Grammar object is not useful as a generic
   * grammar access or query object. In other words, you cannot round-trip
   * specific grammar syntaxes with the compiled grammar information in
   * the Grammar object. You <em>can</em> create equivalent validation
   * rules in your choice of grammar syntax but there is no guarantee that
   * the input and output will be the same.
   * <p/>
   * <p> Right now, this class is largely a shell; eventually,
   * it will be enriched by having more expressive methods added. </p>
   * will be moved from dtd.Grammar here.
