Thanks to this new feature, the FORMAT parameter of GetFeatureInfo for the WMS service may take 'application/json' or 'application/geo+json' values. In this case, the document returned by the server looks something like this:
{"type": "FeatureCollection",
"features":[
{
"type":"Feature",
"id":"testlayer",
"geometry":
{"type": "Point", "coordinates": [913204.9128, 5606011.4565]},
"properties":{
"id":3,
"name":"three",
"utf8nameè":"three"
}
}]
}
