Post a string message to the server log.
The implementation of this method constructs a SIF_LogEntry object
with the LogLevel attribute set to "Info" and the
SIF_Desc element set to the text message passed to
the message parameter. The SIF_LogEntry object is then
reported to the zone as a SIF_Event by delegating to the log
method that accepts a SIF_LogEntry parameter.
