This figure illustrates savepoints (both explicit and implicit) in workspaces, as explained in text after the illustration.
The hierarchy of workspaces is the same as in the preceding figure (Workspace Tree). That is, the LIVE workspace is at the top. Under the LIVE workspace are its two child workspaces, Workspace1 and Workspace4. Under Workspace1 are its two child workspaces, Workspace2 and Workspace3; and under Workspace4 is its child workspace, Workspace5.
