  * Abstract decoder for developing concrete encoders.
  *
  * Concrete implementations extending Decoder will utilize methods on Decoder
  * to decode XML infoset according to the Fast Infoset standard. It is the
  * responsibility of the concrete implementation to ensure that methods are
  * invoked in the correct order to correctly decode a valid fast infoset
  * document.
  *
  * <p>
  * This class extends org.sax.xml.DefaultHandler so that concrete SAX
  * implementations can be used with javax.xml.parsers.SAXParser and the parse
  * methods that take org.sax.xml.DefaultHandler as a parameter.
  *
  * <p>
  * Buffering of octets that are read from an {@link java.io.InputStream} is
  * supported in a similar manner to a {@link java.io.BufferedInputStream}.
  * Combining buffering with decoding enables better performance.
  *
  * <p>
  * More than one fast infoset document may be decoded from the
  * {@link java.io.InputStream}.
