Michael and Pete have already supplied answers to your question, but I
thought it might help to explicitly clarify one additional point --
which is to differentiate the default behavior between declaration and
reference. In this example:

     <xsd:complexType name="complexTypeOne">
        <xsd:sequence>
            ...
            <xsd:element name="SubElementWithoutPrefix"
                  type="ElementTypeWithoutPrefix" /> <!-- a line with
a problem -->
        </xsd:sequence>
    </xsd:complexType>

"SubElementWithoutPrefix" is a local element *declaration*. Because
the <schema> declaration specifies elementFormDefault="qualified",
this element is in the targetNamespace. (If  you didn't have
elementFormDefault="qualified", it would be in no namespace.)

"ElementTypeWithoutPrefix" is a type *reference*. Because no prefix is
explicitly specified, the type is from the default namespace.

Defining elements in a different namespace from their types is a
fairly common practice.

The Sun Java 6 validation is in error. The IBM Java 5 validation is correct.
