Sorry, that's not a problem -- vacuous restriction is allowed.  I
don't know the details of the validator involved, but I would guess
that the problem is that you're using anonymous type definitions -- 
W3C XML Schema requires the type definition of an element in a restriction to be
the same as or derived from the type definition of the corresponding
element, and it only _guarantees_ identity for type definitions with
names.  So move that anonymous definition up to the top level, give it
a name, and refer to it _by_ name, i.e.

  <xsd:element name="FirstElement" type="myChoiceType"/>

in both base and restriction, and you should win.
