    Modified
    The composite form item is modified as soon as one of the form items is modified.
    Expressions
    The composite form item does not support expressions.
    Validation
    The composite form item is valid if all form items are valid. Adding new validation handlers is not supported.
    Restricted
    The composite form item is restricted if any of the form items is restricted.
    Enabled
    The composite form item is enabled if all form items are enabled.
    Required
    The composite form item is required if any of the form items is required.
