• RepeatingElement[spec, max] represents an element that can appear at most max times.
• RepeatingElement[spec, {min, max}] represents an element that can appear between min and max times.
• RepeatingElement[spec, {n, {min, max}}] represents an element that initially appears n times in a form.
• RepeatingElement[spec, {{i, n}, {min, max}}] represents an element where i takes successive values.
