24   wrong schema constraint

Created: 08 Mar 2005

Status: In Force (green)

Part: Part 6 (2004)




Paragraph: Annex A.5

Category: Issue for edition 2 of this part


The uniqueness constraints for GSE and SV in the schema only refer to the cbName. This is too restrictive and inconsistent to the text, the ldInst has additionally to be considered.


Change constraints uniqueGSEinConnectedAP and uniqueSMVinConnectedAP by adding
<xs:field xpath="@ldInst"/> to the existing
<xs:field xpath="@cbName"/>

Discussion Created Status
The remark concerning ldName does not belong here, therefore also the NEGATIVE vote does not concern the real issue, which is just to repair the schema so that it fits to the intentions documented already in part 6. Therefore, the proposal is accepted 13 Jul 05 In Force (green)
NEGATIVE vote by Juan Torres: Needs more explanation 12 May 05 Future Improvement
To 'final proposal': the new LD name attribute should according to the rules be named ldName instead of LDName; further, the additional restriction on ldInst will still be necessary in the case that ldName is not specified and the default ldName= iedName+ldInst is used. 08 Apr 05 Ballot Period
Final Proposal:
change uniqueness definition to unique cbName with LDevice
<xs:field xpath="@LDName"/>
<xs:field xpath="@cbName"/>
01 Apr 05 Ballot Period
The proposed schema change should be done, becuase currently the schema is in contradiction to the text as well as intended control block name space definition. 09 Mar 05 Triage
