/** central interface to query for, create, destroy and manipulate user
    interface elements which are bound to a layout manager.

    <p>
    Every user interface element which is controlled by a layout manager has
    a unique identifier called resource URL.

    A resourcce URL must meet the following syntax:
    "private:resource/$type/$name". It is only allowed to use ascii characters
    for type and name.

    Currently the following user interface element types are defined:
    <ul>
        <li><b>menubar</b>A configurable user interface element representing
        a menu bar.</li>
        <li><b>popupmenu</b>A configurable user interface element representing
        a popup menu.</li>
        <li><b>toolbar</b>A configurable user interface element a tool
        bar.</li>
        <li><b>statusbar</b>A configurable user interfave element representing
        a status bar.</li>
        <li><b>floater</b>A basic user interface element representing a
        floating window.</li>
