Summary0010332: Clarification needed re: type definition in ReferenceDescription
Description

In the definition of https://reference.opcfoundation.org/Core/Part4/v105/docs/7.30 there is a note for the "nodeId" field that says:

If the server Index indicates that the TargetNode is a remote Node, then the nodeId shall contain the absolute namespace URI. If the TargetNode is a local Node the nodeId shall contain the namespace index.

There is no such restriction on the "typeDefinition" field, however I'm finding that some clients do not handle an ExpandedNodeId defined with a URI rather than namespace index correctly for this field (e.g. UaExpert).

Is the intention that both "nodeId" and "typeDefinition" are restricted to a relative namespace index when the type is local to the server, or is this legal and the clients need to be fixed?

Are there backwards compatibility implications if we retroactively add this restriction?

TagsNo tags attached.

Sigh... I got the link syntax backwards but Mantis doesn't let me edit anything.

Add restriction to always use the index form for local nodes in TranslateBrowsePath and Browse (And any other services?).
