Hi Nic, xsd:any is a very specific beast: "In general, an any element specifies that any well-formed XML is permissible in a type's content model" and it doesn't accept xsd:element as its content. My understanding is that you have to use a combinaison of the 3 following elements to try to achieve what you want here: xsd:sequence (imposing an order for your elements). xsd:choice (one of the items only) xsd:all (several restrictions such as maxOccurs for each of the elements can only be <= 1). I may have missed something (I hope so ;) but I don't see how you can achieve declaring (at least in an extensible way) that both aaa and bbb have to be present between 0 to 2 times in any order with the current draft ! The only way I can think of is a xsd:choice between a xsd:sequence for each combinaison. Hope this helps.
