F.19 ReferenceToChange ToC Previous Next

The ReferenceToChange type specifies a single Reference to add to or remove from an AddressSpace.

The elements of the type are defined in Table F.17.

Table F.17 – ReferencesToChange

Element Type Description
Source NodeId The identifier for the source Node of the Reference.
ReferenceType NodeId The identifier for the type of the Reference.
IsForward Boolean TRUE if the Reference is a forward reference.
Target NodeId The identifier for the target Node of the Reference.

References to Nodes that could exist are always allowed. In other words, a Reference is never rejected simply because the target is unknown Node.

The source of the Reference must exist in the AddressSpace or in UANodeSetChanges document being processed.

Reverse References are added when deemed practical by the processor.
