 A component expression is a \lstinline[language=grammar]!component-reference! which is a valid expression, i.e., not referring to models or blocks with equations.
 % "an element of records" below looks strange:
-In detail, it is an instance of a (a) base type, (b) derived type, (c) record, (d) an array of such an instance (a-c), (e) one or more elements of such an array (d) defined by index expressions which are evaluable expressions (see below), or (f) an element of records.

 The essential features are that one or several values are associated with the instance, that start values can be defined on these values, and that no equations are associated with the instance.
 A component expression can be constant or can vary with time.
