This is a text description of Figure 1-3, "Multiparent Workspace in a Workspace Hierarchy". It illustrates a multiparent workspace (Workspace3, having its original parent workspace Workspace1, plus the added parent workspace Workspace4).
In the workspace tree, 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 are its two child workspaces, Workspace3 and Workspace5.
