All examples in the documentation and videos show adding attributes of DR PI Point to event frame templates.
How can you add other attributes that might not be of this type but which are time-dependant?
I can understand how static information such as a description could be inferred back to the reference element, but what about for example an attribute that is a linked Table Lookup DR, where the value may change over time. There seems to be no way to reference such an attribute in the Event Frame. Do you also have to go back to the reference element and re-query based on the event frame time? What if the source data has been removed from the source table in which case such a solution will not work.
