22   * LoggerContextVO offers a restricted view of LoggerContext intended to be
23   * exposed by LoggingEvent to remote systems. This restricted view is optimized
24   * for serialization.
25   * 
26   * <p>
27   * Some of the LoggerContext or Logger attributes MUST not survive
28   * serialization, e.g appenders, level values etc, as these attributes may have
29   * other values on the remote platform. LoggerContextVO class exposes the
30   * minimal and relevant attributes to the remote host, instead of having to deal
31   * with an incomplete LoggerContext with many null references.
