XSD for any order in complex type?

I have a problem generating an XSD. In our application the user can define his own format of data, so the user can define, which data he passes us to a webservice. There he can define, if an element can occur once or often. So I get XML like this:

<WaitForSoap>         
    <Lastname>last</Lastname>
    <Firstname>first</Firstname>
    <Birthday>hallo</Birthday>
    <Firstname>first</Firstname>
    <Firstname>first1</Firstname>
</WaitForSoap>

So what I want now is a XSD which ensures, that lastname, birthday occurs once, firstname occurs 3 times. The order of the elements in WaitForSoap element should be in any order. So xsd:sequence is not right to use here; xsd:all is even not right, because I can't use maxoccurs there. With xsd:choice I did not get the right solution.

Any other ideas what I could do?

Your design is needlessly complex. Impose an ordering on Firstname, Lastname, and Birthday and the complexity all goes away. You'll be able to represent your requirements with simple occurrence constraints in XSD 1.0.

If you insist on allowing any ordering, you won't be able to represent your requirements in XSD 1.0. You'll have to use XSD 1.1 and write assertions over WaitForSoap rather than the more natural minOccurs and maxOccurs constraints on its children.
