 +The optional ''"​**type**"''​ attribute allows to define the type of the map. If no preview is available, the application will use common preview based on the map type. Can be one of ''"​**roads**"'',​ ''"​**topo**"'',​ ''"​**satellite**"'',​ ''"​**hybrid**"'',​ ''"​**nautical**"'',​ ''"​**aeronautical**"'',​ ''"​**historical**"'',​ ''"​**hillshade**"'',​ ''"​**contours**"''​.
  
 An ''​**<​outline>​**''​ tag (pairs of longitudes/​latitudes,​ space separated) can be used to define the area covered by the map.

 The ''​**<​update-delay>​**''​ tag indicates after how many time the stored map data should be updated if it's used again. The default is ''​**None**'',​ meaning the application will never try to update the stored data. Must end with ''​**D**''​ (number of days), ''​**W**''​ (weeks), ''​**M**''​ (months) or ''​**Y**''​ (years). For example, ''​**3M**''​ means 3 months.

 The difference between regular maps and map layers is that a map layer is added over the current map when being selected. This is usually used for maps having a transparent background.

 +===== Force a particular map projection =====
 +\\
 +By default, the application uses the "WGS 84 / Pseudo-Mercator"​ (EPSG:3857) map projection. You can force a different map projection using the ''​**<​projection-code>​**''​ tag:
 +
 +<code xml>

 +  </​source>​
 +</​code>​
 +
 +In case you want to use map projection which is not known by the application,​ you can import its WKT definition:
