Simple question

[Volker Zink]

I am writing my first schema and have 3 complex types which represent
"top level objects":

<complex type name="A1">
....
</complex type>

<complex type name="A2">
....
</complex type>

<complex type name="A3">
....
</complex type>


In the XML-Document i want that there may be any number of
corresponding elements in any order. I.e.

<A1></A1>
<A2></A2>
<A1></A1>
<A3></A3>
<A1></A1>
<A2></A2>

How do i model that in the schema?

I can't use the union, because these are complex types, and all is not
possible too because the number is unbounded. Is there a simple
solution to this simple problem?

Thanks

Declare an unbounded choice element in your schema, e.g.:

<xs:element name="root">
<xs:complexTy pe name="rootType" >
<xs:choice maxOccurs="unbo unded">
<xs:element name="A1"/>
<xs:element name="A2"/>
<xs:element name="A3"/>
</xs:choice>
</xs:complexType>
</xs:element>

Try it out! I hope this is what you where looking for.
