These aren't sufficient.  They work great once you are connected to
a COAS server, but you need sometimes to ask a Trader for a COAS server
that has certain capabilities before connecting to it.   Thus
the service specified below is registered to the Trader by a server so
that a client can "discover" its capabilities before connecting
to it.  This is on page 208 of the March25 spec, so it is already
taken care of.


Service AccessComponent {
  Interface AccessComponent;
  Mandatory readonly property StringSeq 
components_implemented;
  Readonly attribute StringSeq pid_service;
  Readonly attribute StringSeq terminology_service;
  Readonly attribute StringSeq trader_service;
  Readonly attribute StringSeq naming_service;
  Readonly property String component_name;
  Readonly property String component_version;
  Readonly property StringSeq supported_codes;
  Readonly property StringSeq supported_qualifiers;
  Readonly property StringSeq default_policies;
  Readonly property StringSeq supported_policies;
};

Thanks,

Dave
