Definition
----------

* <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>
                * <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> 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.
