Specifically use the table node definition (see Table 2).

Define the property by providing the property name and value, or a description of the value.

Define a reference by providing the reference type name, the browse name of the target node, and its node class.

--- If the target node is a component of the table that defines the node, the properties of the corresponding node are defined in the same row in the table. This means table

In the definition of the node is the target node, the referenced node will have HasModelParent (see IEC 62541-3

In the definition of ModelParents).
