Yes, that should be the minimum anonymous type declaration enbedded in
an element declaration and the result will be an empty element with no
attributes.
The reason for this is that <complexType/> is shorthand for:

<complexType>
   <complexContent>
      <restriction base="anyType">
      </restriction>
   </complexContent>
</complexType>

So, this means we have a complexType that restricts the anyType and
since we don't declare any elements or attributes we get an empty
content model.
