XSD: define 2 elements with the same name but exact definition of attributes

Is there a way to define several attributes with fixed values and subelements for 2 elements with the same name? 

<Root>

  <element 
    attributeA="1" 
    attributeB="2">
    <subElement/>
  </element>

  <element 
    attributeA="3" 
    attributeB="4">
    <subElement/>
  </element>

 </Root>

I want any of this elements to be possible but the following element NOT to be allowed:

<element 
   attributeA="1" 
   attributeB="4">
   <subElement/>
</element>

I know in xsd it is not possible to have 2 elements with the same name under one "parent". to create only on element and restrict it via enumeration does not seem to work since I have to avoid "mixed" forms. The names of the elements have to identical and they have to have the parent element.

Is there a solution I don't see or a workaround for this problem?

Such a model would violate the constraint "Element Declarations Consistent", which requires that if two element particles in a content model have the same name then they must have the same type.

You can do it in XSD 1.1, of course, using assertions.
