 \lstinline!C! is a placeholder for any class, including the built-in type classes \lstinline!Real!, \lstinline!Integer!, \lstinline!Boolean!, \lstinline!String!, and enumeration types.
 The type of a dimension upper bound expression, e.g.\ $n$, $m$, $p$, \ldots in the table below, need to be a subtype of \lstinline!Integer! or \lstinline!EB! for a class \lstinline!EB! that is an enumeration type or subtype of the \lstinline!Boolean! type.
 
-Colon (\lstinline!:!) indicates that the dimension upper bound is unknown and is a subtype of \lstinline!Integer!.  The size of such a variable can be determined from its binding equation, or the
-size of any of its array attributes, see also \cref{flexible-array-sizes-and-resizing-of-arrays-in-functions}.  The size cannot be determined from other equations or algorithm.
