CASL architectural specifications provide a way to specify the structure of the implementations of software systems. Their seman- tics has been introduced in two manners: the first is purely model- theoretic and the second attempts to discharge model semantics condi- tions statically based on a diagram of dependencies between components (extended static semantics). In the case of lambda expressions, which are used to define the way generic units are built, the two semantics do not agree. We present a number of situations of practical importance when the current situation is unsatisfactory and propose a series of changes to the extended static semantics to remedy this.
