    /** provides three types of contents: Link, Folder and Root Folder.

        <p>

        <b>HCP Contents</b>
        <ol>
        <li>
        A HCP Link (HierarchyLinkContent) is a content which
        points to another (UCB) content. It is always contained in HCP Folder.
        A HCP Link has no children.
        </li>
        <li>
        A HCP Folder (HierarchyFolderContent) is a container for
        other HCP Folders and HCP Links.
        </li>
        <li>
        There is at most one instance of a HCP Root Folder
        ( HierarchyRootFolderContent ) at a time.
        All other HCP contents are children of this folder. The HCP Root
        Folder can contain HCP Folders and HCP Links. It has the URL
        "vnd.sun.star.hier:/".
        </li>
        </ol>

        <p><b>URL Scheme for HCP Contents</b>

        <p>Each HCP content has an identifier corresponding to the following
        scheme:

        <ul>
        <li>
            vnd.sun.star.hier:/&lt;path&gt;, where &lt;path&gt; is a
            hierarchical path of the form &lt;name&gt;/.../&lt;name&gt; and
            where &lt;name&gt; is a string encoded according to the URL
            conventions.
        </li>
        </ul>

        <p>Examples:

        <ul>
        <li>
        vnd.sun.star.hier:/ (The URL of the HCP Root Folder)
        </li>
        <li>
        vnd.sun.star.hier:/Bookmarks/Sun%20Microsystems%20Home%20Page
        </li>
        <li>
        vnd.sun.star.hier:/Workplace/Printers
        </li>
        </ul>

        </p>
