text: The main town island of Enniskillen and Castle Island appear to be "missing" (or underwater) on OSM WMS Worldwide see http://osm-wms.de/index.html?zoom=15&lat=54.34537&lon=-7.63301&layers=B000TFT&marker=-7.6389364%2C54.34485380000002
  
  I don't know if this is a problem with the tagging of the 'island' in the middle of the riverbank (as it appears to me to be tagged correctly) or an issue with WMS. The same effect appears with the little islands in Lower Lough Erne
