  39  * \brief Simple attribute initialization routine
  40  *
  41  * The function adds commonly used attributes to the logging system. Specifically, the following
  42  * attributes are registered globally:
  43  *
  44  * \li LineID - logging records counter with value type <tt>unsigned int</tt>
  45  * \li TimeStamp - local time generator with value type <tt>boost::posix_time::ptime</tt>
  46  * \li ProcessID - current process identifier with value type
  47  *     <tt>attributes::current_process_id::value_type</tt>
  48  * \li ThreadID - in multithreaded builds, current thread identifier with
  49  *     value type <tt>attributes::current_thread_id::value_type</tt>
