Interface Base

Upon receipt, this shall cause the message in the passed fields to be appended to the Messages attribute.

If appending the message would cause the number of messages to be greater than the capacity of the list, the device shall NOT append any message to Messages, and shall return a status code of RESOURCE_EXHAUSTED.

When displaying a message in response to this command, an indication (ex. visual) of the origin node of the command shall be provided. This could be in the form of a friendly name label which uniquely identifies the node to the user. This friendly name label is typically assigned by the Matter Admin at the time of commissioning and, when it’s a device, is often editable by the user. It might be a combination of a company name and friendly name, for example, ”Acme” or “Acme Streaming Service on Alice’s Phone”.

NOTE

It is currently not specified where the friendly name label can be found on the node, meaning that clients SHOULD NOT rely on a certain method they happen to observe in a particular server instance, since other instances could employ a different method.

The device SHOULD make it possible for the user to view which nodes have access to this cluster and to individually remove privileges for each node.
