This structured DataType is used to provide a key-value pair for storage outside the context of where the Node is located, using a PortableNodeIdentifier as the key.
The structure is formally defined in Table 180.

Key |
4:PortableNodeIdentifier |
The key to the item. |
|
ArrayIndex |
0:UInt32[] |
If Key refers to a Node of array type, 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 of size 0. |
|
Value |
0:BaseDataType |
The value associated with the key/array item. |
The PortableNodeIdentifierValuePair representation in the AddressSpace is formally defined in Table 181.
