How to redefine default HTTP code if validation is failed?

[yalagtyarzh]

For example, I have struct with validation parameters:

type ShowEventsParams struct {
	Sort        string    `query:"sort" enum:"asc,desc" default:"desc"`
	Offset      uint      `query:"offset" default:"0"`
	Limit       uint      `query:"limit" maximum:"100" default:"10"`
	GroupBy     string    `query:"groupBy" default:"event_time"`
	DateFrom    time.Time `query:"dateFrom" required:"true"`
	DateTo      time.Time `query:"dateTo" required:"true"`
}

If validation is failed, I get back 422 error. Instead of this, I want to receive 400 error. I saw that I can change the response body with Transformer. Is there any mechanism to redefine default validation error response code, like Transformer?
