611 Errorneous MMS example.
Created: 21 Mar 2008
Status: In Force (green)
Part: Part 7-1 (2003)
Paragraph: Fig 61
Category: Issue for edition 2 of this part
There are several flaws in MMS example at Fig 61.
1. Access result for value(s) is represented as "IMPLICIT SEQUENCE OF" (i.e. another nesting level) containing values, while in reality it is a sequence of access results of individual values, in a same nesting level with reason codes that follow.
In combination with somewhat ambiguous definition in IEC61850-8-1->"Access Result for value(s)", page 55 this can be completely misleading
2. The order Value data attributes is incorrect, origin has to be before of stVal.
Correct MMS example or produce one by using a real life MMS message disassemled it with some ASN.1 tool (with subsequent addition of comments)

MMS example will be corrected.
Additionally </RPT> must be replaced by <RPT> and reasoCode type must be BITSTRING.
