Google wrappers proto fails validation

[jtjeferreira]

I was trying this in my project and noticed that it fails for the wrappers.proto from google:

// Wrapper message for `uint64`.
//
// The JSON representation for `UInt64Value` is JSON string.
message UInt64Value {
  // The uint64 value.
  uint64 value = 1;
}

{
    "error_type" : "MessageNameCamel",
    "source" : {
      "name" : "UInt64Value",tocGenerate 0s
      "field" : [
        {
          "number" : 1,
          "name" : "value",
          "label" : "LABEL_OPTIONAL",
          "jsonName" : "value",
          "type" : "TYPE_UINT64"
        }
      ]
    }
  },
  {
    "error_type" : "MessageNameCamel",
    "source" : {
      "name" : "UInt32Value",
      "field" : [
        {
          "number" : 1,
          "name" : "value",
          "label" : "LABEL_OPTIONAL",
          "jsonName" : "value",
          "type" : "TYPE_UINT32"
        }
      ]
    }
  }
