-
-    <para>The selections are used to configure various image
-    processing functionality performed by the subdevs which affect the
-    image size. This currently includes cropping, scaling and
-    composition.</para>
-
-    <para>The selection API replaces <link
-    linkend="vidioc-subdev-g-crop">the old subdev crop API</link>. All
-    the function of the crop API, and more, are supported by the
-    selections API.</para>
-
-    <para>See <xref linkend="subdev"></xref> for
-    more information on how each selection target affects the image
-    processing pipeline inside the subdevice.</para>
-
-    <refsect2>
-      <title>Types of selection targets</title>
-
-      <para>There are two types of selection targets: actual and bounds. The
-      actual targets are the targets which configure the hardware. The BOUNDS
-      target will return a rectangle that contain all possible actual
-      rectangles.</para>
-    </refsect2>
-
-    <refsect2>
-      <title>Discovering supported features</title>
-
-      <para>To discover which targets are supported, the user can
-      perform <constant>VIDIOC_SUBDEV_G_SELECTION</constant> on them.
-      Any unsupported target will return
-      <constant>EINVAL</constant>.</para>
-
-    <para>Selection targets and flags are documented in <xref
-    linkend="v4l2-selections-common"/>.</para>
