Summary0007766: Clarification for UAInstance::ParentNodeId and validation of models
Description

The current definition for optional ParentNodeId is:
The NodeId of the Node that is the parent of the Node within the information model. This field is used to indicate that a tight coupling exists between the Node and its parent (e.g. when the parent is deleted the child is deleted as well). This information does not appear in the AddressSpace and is intended for use by design tools.

Based on this definition, all components of types and of instance declarations have the ParentNodeId set in nodesets published with OPC UA specifications.

This is different in the PackML specification where the ParentNodeId is missing for some nodes (see below - two nodes on the same parent but for the Object the ParentNodeId is missing.

The question is now if we need to be more precise with the requirements (and the use of shall) or if this is just something that was not found by the validation?

Updated F.7 to require that the ParentNodeId be specified for all InstanceDeclarations.

Note that the NodeSet validation process will now discover errors with the ParentNodeId.

Agreed to 1.05.03 text. Needs 1.03 and 1.04 Errata to close -- the Errata should strongly suggest the Parent links be added, but not require it to prevent invalidating existing Nodeset generators.
