Namespace for user-defined types in WSDL?

I obviously am not grokking something about how to properly use namespaces in the XML of a WSDL. Something has just not clicked. I cut out a piece of our WSDL to demonstrate this problem. See below for the working WSDL.

When I use wsimport to generate code from this, it works. When I try to use a type that I defined, it does not. I saw a comment in another question that said:

For example, one does not have to use a prefix for the items defined in the schema,
that are later on referenced elsewhere in the same file (e.g. a global simpleType
used as a type for an attribute or element).

When I read that, I think I understand it. But I obviously do not.

The JAX-WS I am using is: "JAX-WS RI 2.1.6 in JDK 6"

I added this to the WSDL, inside the :

<xsd:complexType name="Void">
    <xsd:sequence>
    </xsd:sequence>
</xsd:complexType>

And I changed the HelloRequest element to:

<xsd:element name="HelloRequest" type="Void" />

And I get the error below.

"one does not have to use a prefix for the items defined in the schema that are later on referenced elsewhere in the same file..."

What does that sentence mean? I do not think it means what I think it means....

</wsdl:service>
</wsdl:definitions>

and the error from running the wsimport is:

It was detected that 'Void' has no namespace, but components with no target namespace are not referenceable from schema document 'http://snip/LMSService.woa/wa/hellowsdl#types?schema1'. If 'Void' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'Void' has no namespace, then an 'import' without a "namespace" attribute should be added to 'http://snip/LMSService.woa/wa/hellowsdl#types?schema1'.

I do not know whether to be surprised about this answer or not.

The complexType I am defining is in the targetNamespace for the schema. I had:

<xsd:schema elementFormDefault="qualified"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            targetNamespace="http://snip/LMSService.woa/wa/mebsoap">

    <xsd:complexType name="Void">
        <xsd:all></xsd:all>
    </xsd:complexType>

    <xsd:element name="HelloRequest" type="Void" />
    ....

I needed to use:

<xsd:schema elementFormDefault="qualified"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            xmlns:tns="http://snip/LMSService.woa/wa/mebsoap"
            targetNamespace="http://snip/LMSService.woa/wa/mebsoap">

    <xsd:complexType name="Void">
        <xsd:all></xsd:all>
    </xsd:complexType>

    <xsd:element name="HelloRequest" type="tns:Void" />
    ....

And that was all it took!
