Issue for edition 2 of this part

Issue

8.1.2.2 states "Values that are less than 0 shall be considered private values. The range of allowed values
are specified in IEC 61850-7-2 and IEC 61850-7-3" while IEC61850-7-3 Table A.5 states negative values for (some) unit multipliers.

Proposal

Remove statement "Values that are less than 0 shall be considered private values.".

DiscussionCreated
Not Applicable A note has been added about the unit multiplier exception.
8-1 can not remap the value of 7-3. However the statement is still correct for other enumerations 		16 Jun 10
