Looks like a bug in the way the "Only show error totals" returns the result. With this example I get validation errors without "Only show error totals" selected: http://validate.open311.org/validate?schema=georeport-v2%2Frequests.json&output=browser&datajson_url=https%3A%2F%2Fopen311-sandbox.6aika.fi%2Fapi%2Fgeoreport%2Fv2%2Frequests.json&qa=false But it shows 100% valid when "Only show error totals" is selected: http://validate.open311.org/validate?schema=georeport-v2%2Frequests.json&totals=true&output=browser&datajson_url=https%3A%2F%2Fopen311-sandbox.6aika.fi%2Fapi%2Fgeoreport%2Fv2%2Frequests.json&qa=false
