                the setting is ignored.</li>
            <li>External components may use the settings to carry arbitrary information with

    /** is a convenience wrapper around the <member>Info</member> property.

        <p>Since fiddling around with a sequence of property values is somewhat uncomfortable
        in all known UNO language bindings (especially for tasks like simply changing the value
        of an existing value), the <member>Settings</member> property wraps the <member>Info</member>
        property for easier single-value access.</p>

        <p>You should use the <member>Setting</member> property if you need to access a few properties only,
        and the <member>Info</member> property if you need access to all existent settings at once.</p>

        <p>The object represented by this property supports the <type scope="com::sun::star::beans">PropertyBag</type>
        service. That is, you can at runtime add arbitrary new properties to the bag.</p>

        <p>Additionally, the property bag supports default values of properties, and thus the
        <type scope="com::sun::star::beans">XPropertyState</type> interface. If you add an own property to
        the bag using <member scope="com::sun::star::beans">XPropertyContainer::addProperty</member>, you need
        to specifiy an initial value, which is also used as default value (exceptions see below).</p>

        <p>Effectively, the property bag represented by <code>Settings</code> contains two classes of properties:
        Pre-defined ones and user-defined ones.</p>

        <p><em>Pre-defined</em> properties are properties which are potentially used by the data source, the
        application UI for the data source, or a particular backend driver employed by the data source. There's
        a large set of such properties, no all of them are effectively used for a concrete data source, nonetheless,
        they're all present in the <code>Settings</code>.<br/>
        Such properties are not removeable from the bag, that is, their
        <member scope="com::sun::star::beans">PropertyAttribute::REMOVEABLE</member> attribute is <em>not</em> set.<br/>
        Usually, you'll find that all of this properties have the
        <member scope="com::sun::star::beans::">PropertyState::PropertyState_DEFAULT_VALUE</member> state.</p>

        <p><em>User-defined</em> properties are the ones which are added at runtime by any instance. They might or might
        not be removeable, this depends on whether or not the code adding them specifies the
        <member scope="com::sun::star::beans">PropertyAttribute::REMOVEABLE</member> attribute. Also, they might
        or might not have a default value, determined by the
        <member scope="com::sun::star::beans">PropertyAttribute::MAYBEDEFAULT</member> attribute at the time they're added
        to the bag.</p>

        <p>When a data source is made persistent, then properties which are not removeable (which are assumed to be the
        pre-defined properties) are ignored when they are in <code>DEFAULT</code> state. All other properties are
        always made persistent, except when an explicit
        <member scope="com::sun::star::beans">PropertyAttribute::TRANSIENT</member> attribute prohibits this.</p>

        <p>Similar, when you obtain the <member>Info</member> property of a <code>DataSource</code>, the
        <code>Settings</code> bag is asked for all its property values, and the ones which are removeable and
        in state default are stripped, and <em>not</em> returned in the <code>Info</code> sequence.</p>
