shorthand define can't custom label?

[vandungbk92]

hello everyone, i have a question with fast validator.
when i full declaration: full_name: {type: string, label: "Full Name"} then message error: The Full Name field is required, but then shorthand declaration: full_name: "string|label:Full Name" error not custom label: The full_name field is required.
i want declaration Shorthand definitions with label?
