Hi Catalin,

XML Spy's XSD implementation is not conformant. You should send them a
bug report.

The <additionalItemName> element is declared with a local declaration
in 3.xsd. When you declare an element locally, the namespace for the
element is either the target namespace for the schema or no namespace;
it depends on the "form" for the element declaration. Since you have
no form attribute on the <xs:element> element declaration, the "form"
comes from the elementFormDefault attribute on the <xs:schema>
element. In this case, it's 'unqualified', which means that the
<additionalItemName> element is in no namespace.

If you want the <additionalItemName> element to be in the core
namespace (the target namespace for 3.xsd), then you should set the
elementFormDefault attribute on the <xs:schema> element to
'qualified' or add a 'form' attribute to the <xs:element> element with
the value 'qualified'.

Not to give you good validation; part of the design of XSD dictates
that elements in different namespaces must be declared in different
