139        <ul><li>Upon creating a connection, for every value in this sequence it's checked

141                the connection supports a setting with the respective name, using its
142                <member scope="com::sun::star::sdbc">XDriver::getPropertyInfo<member> method.br/>
143                If so, the settings is passed to the drivers's

145                the setting is ignored.</li>
146            <li>External components may use the settings to carry arbitrary information with
147                the data source. Usually, this is used to control the behaviour of components
148                working with the data source.</li>

150    */
151	[property] sequence<com::sun::star::beans::PropertyValue> Info;
152
153    /** is a convenience wrapper around the <member>Info</member> property.
154
155        <p>Since fiddling around with a sequence of property values is somewhat uncomfortable
156        in all known UNO language bindings (especially for tasks like simply changing the value
157        of an existing value), the <member>Settings</member> property wraps the <member>Info</member>
158        property for easier single-value access.</p>
159
160        <p>You should use the <member>Setting</member> property if you need to access a few properties only,
161        and the <member>Info</member> property if you need access to all existent settings at once.</p>
162
163        <p>The object represented by this property supports the <type scope="com::sun::star::beans">PropertyBag</type>
164        service. That is, you can at runtime add arbitrary new properties to the bag.</p>
165
166        <p>Additionally, the property bag supports default values of properties, and thus the
167        <type scope="com::sun::star::beans">XPropertyState</type> interface. If you add an own property to
168        the bag using <member scope="com::sun::star::beans">XPropertyContainer::addProperty</member>, you need
169        to specifiy an initial value, which is also used as default value (exceptions see below).</p>
170
171        <p>Effectively, the property bag represented by <code>Settings</code> contains two classes of properties:
172        Pre-defined ones and user-defined ones.</p>
173
174        <p><em>Pre-defined</em> properties are properties which are potentially used by the data source, the
175        application UI for the data source, or a particular backend driver employed by the data source. There's
176        a large set of such properties, no all of them are effectively used for a concrete data source, nonetheless,
177        they're all present in the <code>Settings</code>.<br/>
178        Such properties are not removeable from the bag, that is, their
179        <member scope="com::sun::star::beans">PropertyAttribute::REMOVEABLE</member> attribute is <em>not</em> set.<br/>
180        Usually, you'll find that all of this properties have the
181        <member scope="com::sun::star::beans::">PropertyState::PropertyState_DEFAULT_VALUE</member> state.</p>
182
183        <p><em>User-defined</em> properties are the ones which are added at runtime by any instance. They might or might
184        not be removeable, this depends on whether or not the code adding them specifies the
185        <member scope="com::sun::star::beans">PropertyAttribute::REMOVEABLE</member> attribute. Also, they might
186        or might not have a default value, determined by the
187        <member scope="com::sun::star::beans">PropertyAttribute::MAYBEDEFAULT</member> attribute at the time they're added
188        to the bag.</p>
189
190        <p>When a data source is made persistent, then properties which are not removeable (which are assumed to be the
191        pre-defined properties) are ignored when they are in <code>DEFAULT</code> state. All other properties are
192        always made persistent, except when an explicit
193        <member scope="com::sun::star::beans">PropertyAttribute::TRANSIENT</member> attribute prohibits this.</p>
194
195        <p>Similar, when you obtain the <member>Info</member> property of a <code>DataSource</code>, the
196        <code>Settings</code> bag is asked for all its property values, and the ones which are removeable and
197        in state default are stripped, and <em>not</em> returned in the <code>Info</code> sequence.</p>
