Isn't this an unordered list of elements? <!ELEMENT BAG (A?,B?,C?,D?)+> Which appears to have order, but as elements are optional and the group is repeatable the ordering isn't enforced. Although the bag can't be empty. So, you could have... <!ELEMENT BAG (A?,B?,C?,D?)*> Which allows an empty BAG Or am I completely wrong? Cheers, L. xml-dev: A list for W3C XML Developers.
