Described are techniques for processing an instance of a data structure. A request to process an instance of a data structure at a first point in time is received. At least one of the data elements in the data structure is a dynamic data element that uses an association specifying how to access data for the dynamic data element in accordance with criteria evaluated using a current context determined at a point in time. In response to receiving the request, first processing is performed including determining whether the dynamic data element is referenced at the first point in time, and, if so, evaluating the criteria using a current context determined at the first point in time, and retrieving data for the dynamic data element in accordance with a current context determined at the first point in time.
