DSS2 — Figure 3: Lifetime of a Federate: Meaning of Save In Progress

Many services in 1516.1 have preconditions and exceptions that are worded simply "Save in progress" or "Save not in progress". However, these states do not appear to be well-defined in the standard. It should be made clear that these are meant to refer to the "Federate Save in Progress" state as shown in the statechart in Figure 3. A save is considered to be in progress at a given federate if the federate is in the "Federate Save in Progress" state.

The definition of these pre-conditions should be clarified.
