Vaidating XML against DTD problem!

Please look at the following xml and the corrosponding DTD
Using XML Spy: My XML file is well formed but when I validate it against it's corrosponding DTD it gives an error saying: file is not valid Unexpected child element '2'. I don't know what's wrong, is there a problem in the DTD. <0> contains zero or more <1> and <1> contains zero or more <2> and <3>. Any help is appreciated. Thanks
