Jeni, Actually, NumWafers and Wafers are mandatory, they just want them in any order. It's everything in : <xsd:extension base="Type_ToolLotSummary"> The Type_ToolLotSummary, which is above <xs:all> that is optional (everyting), and also needed to be in any order. Dumb question : Is <xs:???> and <xsd:???> the same thing? Regardless, I really appreciate the help, Jeni. While I'm extremely curious how I can get this working in the future, the project is currently on the back burner, as other tasks have taken higher priority. I probably won't be able to get back to the schema for another 2-3wks.

In: <xs:sequence minOccurs="0"> <xs:element name="NumWafers" type="xsd:nonNegativeInteger" /> <xs:element name="Wafers" type="WaferLocations" /> </xs:sequence> the sequence as a whole is optional. You are saying that *either* you have a sequence comprising a <NumWafers> element followed by a <Wafers> element, or you have nothing at all. If you want to say that a particular element is optional, use minOccurs="0" on the <xs:element> element for that element. I was actually misremembering the spec; putting minOccurs="0" on an <xs:all> element is fine. You should be able to do: <xs:all minOccurs="0"> <xs:element name="NumWafers" type="xsd:nonNegativeInteger" /> <xs:element name="Wafers" type="WaferLocations" /> </xs:all> in order to get <NumWafers> and <Wafers> to appear in any order.
