Re: Problems with Simple XML Validation

1. In your XMLSchema your default namespace ("") is different from 
targetNamespace ("AnotherTestSpace"). So, the declaration:
 
   <xsd:complexType name="order">
      ...
   </xsd:complexType>

puts "order" in targetNamespace. But, when you refer it:

   <xsd:element name="shipOrder" type="order"/>
   
it tries to find "order" in default namespace, as "order" is not prefixed, and 
is unable to find it. This problem is everywhere in your schema.

[Define a default namespace equal to targetNamespace OR define a namespace equal 
to your targetNamespace and use that prefix when referring.]

2. You have not specified elementFormDefault attribute in your schema file. This 
means it defaults to "unqualified". Therefore in your instance file, you need to 
qualify *only* the global declarations.

[Define a namespace equal to targetNamespace and qualify the global elements in 
your xml file OR set elementFormDefault to qualified and define a default 
namespace equal to targetNamespace in your instance file.]

Hope this helps.
