 * This factory is used to build a resource delta that represents a proposed
 * change that can then be passed to the
 * {@link ResourceChangeValidator#validateChange(IResourceDelta, IProgressMonitor)}
 * method in order to validate the change with any model providers stored in
 * those resources. The deltas created by calls to the methods of this interface
 * will be the same as those generated by the workspace if the proposed
 * operations were performed, except an additional
 * {@link IResourceDelta#DELETE_CONTENT_PROPOSED} flag can indicate if the
 * change is going to delete resources not only from the workspace model but
 * also physically, so it cannot be undone.
 * 
 * This factory does not validate that the proposed operation is valid given the current
 * state of the resources and any other proposed changes. It only records the
 * delta that would result.
