Issue

The description of the CDCs contains the relation between services and FCs. This is however not complete for all possible applications:
- the relation to Logging is not contained at all
- the sending of GOOSE and SV is limited to process values (fc=ST, MX). However, with the extensions of edition 2 it makes also sense to contain here fc= BL, OR, CF, SV, may be sometimes even SP and SG.

Proposal

Allow the sending of attributes / FCDA with fc=BL, OR, CF, SV, SP and SG in GOOSE and SV messages. Add the log (entry) generation identical to reporting.

The result of BL and SV attributes can be seen in the q attribute, and SR is anyhow special for service tracking. However SG makes sense to transmit e.g. with a triggering Op or Str. Therefore 7-3 should be modified to allow attributes with FC = OR, CF, SP and SG in GOOSE messages: as the values of these attributes are always valid, no special update of the Annex A in 7-4 is needed. The interpretation anyhow depends on the function of the receiving subscribers and accompanying process values.	01 Mar 12	Ballot Period
The FC: BL, SV, SR should not be sendable by GOOSE. SG has no triger option, can therefore not be reported; to be consistent, it should not be "goosable". OR, CF and SP should be allowed as GOOSE members.	03 Nov 11	Discussion (red)
If these CDCs are to be contained in e.g. GOOSE, then -7-4 Annex A Interpretation of mode and behaviour shall be updated accordingly. i.e. In Table A.2 -Definition of mode and behaviour, the left most column states on "Output to ST, MX"...	07 Jul 11	Ballot Period
