It gives flexibility to the bot builders to define any format he likes to.
Ex: When we take postal code from the visitor, it should be validated according to the applicable local formats. In US, they use 5-digit numerics, while in India, we use 6-digit numeics. In UK, they use 6-8 characted alpha numerics.
