Derivation by restriction

Would I be correct in concluding that when deriving a complex type by 
restriction, while it is possible to make an optional attribute mandatory in 
the subtype, it is not possible to make the presence of an element 
mandatory?

If so, why not?  If this does not offend the concept of inheritance 
overriding in the case of an attribute why has this facility not been 
implemented for elements?

Cheers Jack
