I did some testing with XML Spy a couple of weeks ago and I found lot's of bugs when using <any> element and <anyAttribute>. I posted a message to XML Spy with all the errors I found but I never got a reply... > This has also got me to wondering about the ordering/precedence of > extensions.

If the type "USAddress" would be declared as: <complexType name="USAddress"> <complexContent> <extension base="ipo:Address"> <choice> <element name="state" type="ipo:USState"/> <element name="zip" type="positiveInteger"/> </choice> </extension> </complexContent> </complexType> If you resolve the content model of "USAddress" it would look like this: <complexType name="USAddress"> <sequence> <element name="name" type="string"/> <element name="street" type="string"/> <element name="city" type="string"/> </sequence> <choice> <element name="state" type="ipo:USState"/> <element name="zip" type="positiveInteger"/> </choice> </complexType> Which means an instance must have <name>, <street> and <city> in sequence followed by a choice of either <state> or <zip>.
