+    <para>To query the attributes of a video standard,
+especially a custom (driver defined) one, applications initialize the
+<structfield>index</structfield> field of &v4l2-standard; and call the
+<constant>VIDIOC_ENUMSTD</constant> ioctl with a pointer to this
+structure. Drivers fill the rest of the structure or return an
+&EINVAL; when the index is out of bounds. To enumerate all standards
+applications shall begin  at index zero, incrementing by one until the
+driver returns <errorcode>EINVAL</errorcode>. Drivers may enumerate a
+different set of standards after switching the video input or
+output.<footnote>
+        <para>The supported standards may overlap and we need an
+unambiguous set to find the current standard returned by
