Struct port designation and OPC access level

Hello,

I am trying to understand whether the OPC server propagates port designation of a user defined structured variable to its children as access levels?

As an example, my user defined structure is MyStruct with children Child1 and Child2. I assign variable MyVar to the type MyStruct and assign it port OUT and expose on OPC. Will MyVar.Child1 and MyVar.Child2 have read-only access to any OPC client connected to the server?
