2. Of course, calls and other depends-on relations must be given their due. If a program in the subset calls, includes, or inherits from another program but doesn’t use it, the compiler is still going to expect that program to be present. But if it isn’t used, there need not be a correct implementation of it: a simple stub, possibly returning a pro forma result, will do just fine.

Chapter 4

1. The term service here designates a generic operation or function that can be invoked via a call-return connector; it does not refer to services as in service-oriented architecture.

Chapter 7

1. Examples of relations that don’t involve an interaction include is a subclass of and decomposition.

E. Epilogue

1. Now that ISO has adopted the IEEE standard, the two organizations will undertake a coordinated update to both the ISO and IEEE standards. This section describes the standard as reflected by Committee Draft 1 (CD1), dated January 2009 (ISO/IEC CD1 42010 2009). The material in this draft had undergone substantial technical review within the working group but had not been formally balloted at the time this chapter was written.
