* This class defines the workflow interface. There can be two
* implementations for the workflows.
*
* In the first workflow implementation a workflow is a list of
* structured tasks (aka workflow element). Each task is working
* on a set of data being identified by a base DN. The order of the
* tasks and their synchronization are defined statically by a task
* tree.
*
* In the second workflow implementation each workflow is a node
* in a workflow tree (aka worflow topology). Each node in the tree
* is linked to a workflow object of the first implementation and the
* base DN of the node is the base DN of the attached workflow object.
* The relationship of the nodes in the tree is based on the base DNs
* of the nodes. A workflow node is a subordinate of another workflow
* node when the base DN of the former is a superior of the base DN of
* the latter. Workflow topology are useful, for example, in subtree
* searches: search is performed on a node as well as on all the
* subordinate nodes.
