/** provides update control for a hierarchy of configuration items
and information about the hierarchy as a whole as well as its root.
<p>Extends AccessRootElement by adding support for
collecting changes and applying them to a backend store as a single batch.
</p>
<p>An implementation represents the root of a partial hierarchy. [See the
documentation for AccessRootElement]. The hierarchy in turn is
a <em>view</em> onto a fragment of persistent data tree that can be accessed
through several such views, or even several processes, simultaneously.
</p>
<p>Elements of the hierarchy, such as descendants of this root element,
may support modification by providing appropriate
interfaces. Changes done this way initially only affect these objects
themselves and other objects within the same hierarchy, such as other
descendants of this root element.
</p>
<p>The accumulated changes within this hierarchy can be managed using
com::sun::star::util::XChangesBatch. Pending changes
will become persistent and visible from other overlapping hierarchies
only when com::sun::star::util::XChangesBatch::commitChanges()
is called. If the hierarchy is disposed or discarded without committing
changes, the changes will be lost.

data set, when
com::sun::star::util::XChangesBatch::commitChanges()
