Furthermore, in the definition of altType, the definition of the id attribute
should be removed, because it is a duplicate (it is already present in the type
being extended).

(Actually, the spec is open to interpretation here. The set of attribute uses
is formed as a union of the attribute uses defined on the base type and the
extended type, and the concept of union depends on the concept of component
identity which is not clearly defined. If the two attribute uses are considered
to be identical, then the union contains only one copy, so there is no error.
But the validity of the S4SD shouldn't depend on this interpretation.)
