  class Form
    # This class represents a select list where multiple values can be selected.
    # MultiSelectList#value= accepts an array, and those values are used as
    # values for the select list.  For example, to select multiple values,
    # simply do this:
    #  list.value = ['one', 'two']
    # Single values are still supported, so these two are the same:
    #  list.value = ['one']
    #  list.value = 'one'
