The errors aren't very helpful :) But this is just a namespace
problem. In your schema, you have the attribute id declared at the top
level of the schema, and therefore in the 'model' namespace. In your
instance document, you've got an id attribute that isn't qualified
with a prefix, and thus is not in a namespace.

So the first error message is complaining that you haven't got a
model:id attribute on the person element.

And the second error message is complaining that you've got an
undeclared id attribute (in no namespace) on the person element.

To fix it, either add the model namespace declaration to your instance
document and use:

  <person model:id="...">...</person>

Or change your schema so that the attribute is declared locally and
thus unqualified:

<element name="persons" minOccurs="0" maxOccurs="1">
  <complexType>
    <sequence>
      <element ref="model:person" minOccurs="1" maxOccurs="unbounded"/>
    </sequence>
    <attribute name="id" type="model:KeyType" use="required"/>
  </complexType>
</element>

Cheers,

Jeni
