The NodeIdentifierValuePair is used to provide a key-value pair where the key is a Variable Node.
It is semantically equivalent to the PortableKeyValuePair as defined in 10.31 with the optimization as described in F.1.2.2.
The NodeIdentifierValuePair DataType is formally defined in Table F.27.

|
ArrayIndex |
0:UInt32[] |
If Key refers to a Variable with ValueRank >= 1, the ArrayIndex specifies the index for a specific value referenced by Key (Not the entire array, but a specific element in it). The ArrayIndex is required to have the same dimension as the dimension of the node. If Key is not of array type, or if no specific index shall be referenced, then the array shall be null or empty. |
|
Value |
0:BaseDataType |
The value associated with the key/array item. |
The NodeIdentifierValuePair representation in the AddressSpace is formally defined in Table F.28.
