NodeID has to have a value?

Hi, i am wondering if NodeID for all CObjects is something that has to have a value? In the AOM documentation it says: “Semantic id of this node, used to differentiate sibling nodes of the same type. [Previously called ‘meaning’]. Each node_id must be defined in the archetype ontology as a term code.”

According to the soruce code of LinkEHR NodeID has to exist. I am just trying to make sure that is the case.

Cheers
