Thats right, but now you can only have one item of each sort. And that exactly is my problem, would need a coice where each item can appear more than one time.Thanks for trying !

My problem is to define a schema for a file like: <Root> <Elemant1/> <Elemant2/> <Elemant3/> <Elemant3/> <Elemant2/> <!--optional<ElemantX/>--> <Elemant3/> <Elemant4/></Root> my problem is the repeating of elements and the optional elements.I tried the following schema: ...<sequence minOccurs=0 maxOccurs=unbound> <Elemant1/> <Elemant2/> <Elemant3/> <ElemantX/> <Elemant4/></sequence>... but now the order is fix, if I use <all> I can't define more than one occurance of an element.Thanks for Help
