> In this case, each ApplyStyleCommand of step 1 and 2 will generate a bunch of SimpleEditCommands.  But we need some way to group commands together so that we can undo only SimpleEditCommands added by step 2 in step 3.  If we didn't have CompositeEditCommand at undo/redo, how do we determine that?

The chain of undo steps would have markers to say where an end user command started. This could be another type of UndoStep object. This marker could also contain the user-visible name of the command.
