<p>A hierarchy data source provides access to a tree of hierarchy data
nodes. Each hierarchy data node, except the root node, has a parent that
is a hierarchy data node too. A hierarchy data node has a name.
<p>Each hierarchy data node has three data members:
<ul>
<li>"Title", which is of type `string`. It contains a title
for the node. This value must not be empty.
<li>"TargetURL", which is of type `string`</li> It may contain
any URL, which will be treated as the target of a hierarchy link.
<li>"Children", which is of type HierarchyDataReadAccess or
of type HierarchyDataReadWriteAccess</li>, depending on the
type of the node. This member provides access to the children of a node.
</ul>
