About Modifiers in Element Definitions in DTDs

When you define an element, you specify one or more modifiers. A modifier specifies a rule about the structure or occurrence of the element being defined. An element can have only one top-level modifier. However, you can add one or more modifiers to the top-level modifier. A modifier can aggregate elements or other modifiers.
