+Map Context Support Through WMS
+-------------------------------
+
+MapServer can also output your WMS layers as a Context document.  MapServer
+extends the WMS standard by adding a request=GetContext operation that allows
+you to retrieve a context for a WMS-based mapfile with a call
+like:
+
+::
+
+    http://localhost/mapserver.cgi?map=/path/to/mapfile.map&service=WMS&
+    request=GetContext&version=1.1.0
+
+The VERSION parameter controls the version of context document to return.
+
+GetContext is disabled by default because it could be
+considered a security issue: it could publicly expose the URLs of WMS layers
+used (cascaded) by a mapfile.
+
+To enable it, set the "wms_getcontext_enabled" web metadata to "1" in your
+WMS server's mapfile.
