title: OPC-UA server with multiple nodes using eclipse milo
body: <p>I am building a OPC-UA server using eclipse milo. What are the different ways to provide multiple nodes for a subscription service? Can I define a custom data object having properties of basic data types, for this? How?</p>
  
  <p>I want to have a service which serves data of different data types (Integer, Double, Boolean etc.) as it's output. Each of the values should be named different not single name like array output with single name for all of the values. For this purpose is there a way to define a custom data object class with attributes of different types? Is this possible in OPC to have a custom data object type as output of a service?</p>
