It's 1.1.4 that is relevant, if I remember your initial question correctly.
1.1.4  Either the {content type} of the {base type definition} and the 
       {content type} of the complex type definition itself must be the same
       simple type definition, or else the {content type} of the complex type 
       definition itself must specify a particle and either the {content
       type} of the {base type definition} must be empty or
    1.1.4.1  both {content type}s must be mixed or both must be element-only;  
    1.1.4.2  the particle of the complex type definition must be a valid
        extension of the {base type definition}'s particle, as defined in
        Particle Valid (Extension) (5.10).
