Ability to remove default error schema?

So, I notice that there's `ErrorModel` schema on my generated swagger. I narrow down the code to this code
```go
// defineErrors extracts possible error responses and defines them on the
// operation op.
func defineErrors(op *Operation, registry Registry) {
exampleErr := NewError(0, "")
errContentType := "application/json"
if ctf, ok := exampleErr.(ContentTypeFilter); ok {
errContentType = ctf.ContentType(errContentType)
}
errType := deref(reflect.TypeOf(exampleErr))
errSchema := registry.Schema(errType, true, getHint(errType, "", "Error"))
for _, code := range op.Errors {
op.Responses[strconv.Itoa(code)] = &Response{
Description: http.StatusText(code),
Content: map[string]*MediaType{
errContentType: {
Schema: errSchema,
},
},
}
}
if len(op.Responses) <= 1 && len(op.Errors) == 0 {
// No errors are defined, so set a default response.
op.Responses["default"] = &Response{
Description: "Error",
Content: map[string]*MediaType{
errContentType: {
Schema: errSchema,
},
},
}
}
}

```
In here, it enfore creation of the `ErrorModel` and `ErrorDetail`. Not mention of the `default` response too. It was everything under this block.
