 The declaration of a component states the type, access, variability, data flow, and other properties of the component.

 A \emph{type} can conceptually be viewed as a \emph{set of values}. When
 we say that the variable \lstinline!x! has the type \lstinline!Real!, we mean that the value of
-\lstinline!x! belongs to the set of values represented by the type \lstinline!Real! i.e.,
