+<h4>Listing Breakpoints</h4>
+The PDA Breakpoints service tracks the inserted breakpoints using the <span
+ style="font-style: italic;">fBreakpoints</span> field.&nbsp; Returning
+the list of breakpoints only requires returning the current state of
+this field.<br>
+<h4>Retrieving Breakpoint Detailed Data</h4>
+The simple PDA debugger does not track detailed breakpoint data, such
+has hit counts, addresses etc.&nbsp; So this function simply returns an
+error.<br>
+<h3>Breakpoints Mediator</h3>
+With the APIs for managing IDE and Target-Side breakpoints clearly
+defined, there is a need for a component which will keep the two sets
+of breakpoint objects synchronized.&nbsp; DSF provides a standard
+BreakpointsMediator service to accomplish this task.&nbsp; <br>
