    ## Extensions enabled by default
    # Any of these extensions can be disabled for a
    # given input by passing: `f.input EXTENSION_NAME => false`.
    # You can make any of these extensions optional by
    # renaming `b.use` to `b.optional`.

    # and required attributes

    ## Optional extensions
    # They are disabled unless you pass `f.input EXTENSION_NAME => true`
    # to the input. If so, they will retrieve the values from the model
    # if any exists. If you want to enable any of those
    # extensions by default, you can change `b.optional` to `b.use`.
