A config option you can use at run time defines the topLevelEntities, a JSON Object.

const config ={
	topLevelEntities:
		 { "JSON PATH" : "Entities @ the JSON PATH specified" 
	},
};

For example, where the Patient Entity is at root:

topLevelEntities: { "
quot; : "Patient" }

In another example, there are three top-level entities, so you use a comma-separated array:

topLevelEntities: { "
quot; : ["Cargo", "FlightPlan", "Aircraft"]}
