I agree with the definition. My suggestion was to make the 2 concepts you mentioned 'properties' of (any applicable) data element, instead of data elements themselves.
If we are to create data elements for all conditions need to be under surveillance, we need to create 2 data elements per condition (suspected and outbreak) I think. However, if suspected (property:under surveillance) is a property of any data element, we don't have to create new data elements and enter data. We can just re-use the data entered and when counts reach the level (property:upper limit to be notified as outbreak), can be visualized and trigger alerts. If we do this, we can keep more than one condition dynamically under surveillance easily.
