I am an idiot :(((((

I have meant xsd:all and therefore:

<xsd:element name="XXX">
 <xsd:complexType>
 <xsd:all>
     <xsd:element name="aaa" maxOccurs="2"/>
     <xsd:element name="bbb" maxOccurs="2"/>
 </xsd:all>
 </xsd:complexType>
</xsd:element>


Is now:

<XXX>
   <aaa/>
   <bbb/>
   <aaa/>
   <bbb/>
</XXX>

valid :)
