Paragraph: first paragraph

Issue: Data Model namespace declarations for extensions by product standards have been clarified in the Ed2.1 amendment of IEC 61850-7-1. The concluded approach is machine processable and takes the presence conditions and rules defined by the product standard into account.

Proposal: Replace the second sentence in the first paragraph:

The value of dataNs data attributes of these extended data objects shall be “IEC 61869-9:2016”.

by the following statement:

In accordance with IEC 61850-7-1, the data model namespace shall be declared in LPHD.NamPlt.lnNs as “IEC 61869-9:2016”.

IEC 61850-7-1 Ed2.1 clause J.8 (normative) prescribes the declaration of lnNs as "IEC 61869-9:2016", in order to account for the presence conditions of the product standard.
