The CustomMetaDataRef Property references another SerializedData Variable. The Value of this Property is the NodeId of this other Variable. A KeyValuePair with the BrowseName of this Variable as key and the NodeId of this Variable as value is added to the content of the Properties KeyValuePair array in the FieldMetaData.

If the CustomMetaDataProperties and the CustomMetaDataRef Properties are both provided, the contents of both are combined in the Properties KeyValuePair array in the FieldMetaData Structure.

Note: As all metadata created by the PubSub mechanism are omitted, the metadata does not contain type information.
