<para>Return the geometry as a Geography Markup Language (GML) element. The version parameter,
if specified, may be either 2 or 3. If no version parameter is
- specified then the default is assumed to be 2. The third argument
+ specified then the default is assumed to be 2. The precision argument
may be used to reduce the maximum number of decimal places
used in output (defaults to 15).</para>
<para>GML 2 refer to 2.1.2 version, GML 3 to 3.1.1 version</para>
- <para>The last 'options' argument is a bitfield. It could be used to define CRS output type
+ <para>The 'options' argument is a bitfield. It could be used to define CRS output type
in GML output, and to declare data as lat/lon:
