+            The Zoom client allows the programmatic zoom of tiled layers (TMS, TileCache, WMS-C, WMTS and XYZ) if a 
+            map resolution is not present in the layer server resolution.

+                This example presents ths usage of the client zoom for the OSM layer.
+            </p>
+
+            <p>
+
+                This example demonstrates the <strong>"client zoom"</strong>
+                functionality.
+
+                The map works with 22 resolutions. But the OSM layer is
+                configured as its tile service supported only 19 of these
+                resolutions. The resolutions for the zoom levels 20,21 and 22 are
+                indeed not included in the OSM layer's
+                <code>serverResolutions</code> option.
+
+                The map's initial zoom is 18. So if you zoom in or out
+                you'll see that "client zoom" is applied
+
+            </p>

+                zoomclient.js source</a> to see how this is done.
