Depending on the data being entered, a mobile device should display the keyboard that is
        appropriate for the data. 
        There are a variety of keyboard types for mobile devices. A field dedicated to phone
            number input should display a keyboard easying phone number input.
        The 
KEYBOARDHINT form field attribute provides a hint regarding the kind
            of data the form field contains. Valid values include 
DEFAULT,
            
EMAIL, 
NUMBER, and
            
PHONE:

        Although Genero mostly respects the provided hint, the variable data type that is bound
            to the form field is also examined, to determine what keyboard to display:
            - If the field is defined as a DATE or DATETIME
                field, the date picker displays regardless of the KEYBOARDHINT
                setting.
 
            - If the field is a TEXT data, a text keyboard displays regardless of
                the KEYBOARDHINT setting.
