Comment (by Thomas M. Bernal <tbernal@…>):

 It seems the severity_logger cheats!

 {{{
 #!cpp
     record open_record_unlocked(ArgsT const& args)
     {
         m_SeverityAttr.set_value(args[keywords::severity |
 m_DefaultSeverity]);
         return base_type::open_record_unlocked(args);
     }
 }}}

 So you are telling me that if I want to add attributes in the call to
 {{{open_record}}} that I need to implement my own logger and cheat? This
 is not the way the library appears to be in the tutorial. The tutorial
 makes it seem that anything passed into {{{open_record}}} will get
 combined with the logger's attributes before being sent to the core. This
 is not only very deceiving but highly cryptic.
