+----------
+
+* <wrmap>...</wrmap> has to be valid XML.
+* All coordinates are in WGS84 coordinate system.
+* Coordinates have the preferred format "latitude N longitude E",
+ however for parsing the N and E can be omitted.
+* <wrmap> has the following attributes:
+ * lat (float): latitude of map-center, optional.
+ * lon (float): longitude of map-center, optional.
+ * zoom (integer): zoom level of the map (google zoom levels). optional.
+ * width (integer): width of the map in pixel. optional (100% if omitted)
+ * height (integer): height of the map in pixel. optional.
+ * <wrmap> can have any number of the following sub-elements:
+ * <gasthaus>
+ * <haltestelle>
+ * <parkplatz>
+ * <achtung>
+ * <foto>
+ * <verleih>
+ * <punkt>
+ * <rodelbahn>
+ * <alternative>
+ * <gehweg>
+ * <lift>
+ * <anfahrt>
+ * <linie>
+ * The order may be used by the renderer to determine in which order the
+ elements should be drawn.
+* <gasthaus>, <haltestelle>, <parkplatz>, <achtung>, <foto>, <verleih> and <punkt> define points
+ * The elements may have the following attributes:
+ * name (string): defines the name (not the label) of the element
+ * wiki (string): name of a MediaWiki page the point refers to
+ * The content is exactly one coordinate pair.
+* <rodelbahn>, <alternative>, <gehweg>, <lift>, <anfahrt> and <linie>
+ define non-closed polygons.
+ * They may have the following attributes:
+ farbe (hex format, e.g. #12a50f): color of the line
+ dicke (int): width of the line in pixel
+ * The content of the elements are a whitespace separated list of
+ coordinates.
+
+
+For transmitting the map to javascript, geojson is used in the <div> element of the map.
+This way, an extra request is avoided. The geojson format used here consists of a single
+"FeatureCollection" (representing the <wrmap>) containing the sub-elements of wrmap
+as features.
+The features have an properties key that has a hash as values with the properties of
+the XML subelements of wrmap. Optional attributes/properties can be omitted.
+Additionally one mandatory property key is called 'type' and has the sub-element's name
+as value.
+The featurecollection itself has a properties key as well containing the attributes of
+the wrmap element.
