I've encountered :

<xs:element name="emptyResponse">
   <xs:complexType>
     <xs:sequence/>
   </xs:complexType>
</xs:element>

in some WSDLs for an empty/null response message
element. .NET and others generate a method 
returning void.

So have contributed the examples:

   <e:example xml:id="EmptySequence" element="emptySequence">
      <e:typedef>
        <xs:element name="emptySequence">
           <xs:complexType>
             <xs:sequence/>
           </xs:complexType>
        </xs:element>
      </e:typedef>
      <e:instance xml:id="emptySequence01">
         <ex:emptySequence/>
      </e:instance>
   </e:example>

to accompany the other two from Ed:

    <e:example xml:id="NullEnumeration" element="nullEnumeration">
      <e:typedef>
        <xs:element name="NullEnumeration" type="ex:NullEnumeration"/>
        <xs:simpleType name='NullEnumeration'>
          <xs:restriction base='xs:string'>
             <xs:enumeration value=''/>
          </xs:restriction>
        </xs:simpleType>
      </e:typedef>
      <e:instance xml:id="nullEnumeration01">
         <ex:nullEnumeration/>
      </e:instance>
   </e:example>

   <e:example xml:id="EmptyComplexType" element="emptyComplexType">
      <e:typedef>
        <xs:element name="emptyComplextType">
           <xs:complexType/>
        </xs:element>
      </e:typedef>
      <e:instance xml:id="emptyComplexType01">
         <ex:emptyComplexType/>
      </e:instance>
   </e:example>
