A binding table version has links to each of the components of a composition at a particular point in time. However, the bound links to components are not represented in the binding table version. (This means that to build up the complete composition, we need both the binding table and the presentation description object.) The history of the binding table represents the history of the composition, with each binding table version representing a version of the composition.
The binding table versions (see figure 7) have two special link names: COMPOSITION:Root which contains a version of the root of the composition. This might look something like
COMPOSITION:Root <313:24>
.
COMPOSITION:Components contains for each unbound component one version of the component. Again, this would have a series of labels such as \
<214:12>,<215:4>
.
