 /**
  * Encodes a {@link Message} (its XML infoset and attachments) to a sequence of bytes.
  *
  * <p>
  * This interface provides pluggability for different ways of encoding XML infoset,
  * such as plain XML (plus MIME attachments), XOP, and FastInfoset.
  *
  * <p>
  * Transport usually needs a MIME content type of the encoding, so the {@link Codec}
  * interface is designed to return this information. However, for some encoding
  * (such as XOP), the encoding may actually change based on the actual content of
  * {@link Message}, therefore the codec returns the content type as a result of encoding.
  *
  * <p>
  * {@link Codec} does not produce transport-specific information, such as HTTP headers.
  *
  * <p>
  * {@link Codec} implementations should be thread-safe; a codec instance could be used
  * concurrently in multiple threads. If a codec have to generate or use a per-request
  * state, the codec implementation must store the state in the Packet instead of using an
  * instance variable of the codec implementation.
  *
  * <p>
  * {@link BindingID} determines the {@link Codec}. See {@link BindingID#createEncoder(WSBinding)}.
