 \indextext{type!fundamental}%
 The types described in this subclause
 are called \defnx{fundamental types}{fundamental type}.
+The representation of a fundamental type is unspecified
+except as stated in this subclause.
 \begin{note}
 Even if the implementation defines two or more fundamental types to have the
 same value representation, they are nevertheless different types.
