30  * Implementation of <code>ConfigurationDocumentLink</code>. This is
31  * probably the only implementation that will ever be needed. It does not
32  * contain any logic specific to a data store so a new implementation should
33  * not be required when new data stores are introduced. The only thing that
34  * should be variable is which factory is used to create a link.
