ABSTRACT
Chapter Summary In this chapter, we introduce XML-based variant configuration language (XVCL) mechanisms to realize the mixed-strategy approach. First, we explain the rationale for XVCL in the context of maintenance changes and evolution. We introduce step-by-step XVCL commands in a series of examples, explaining their role in handling various types of changes and evolution situations. In Section 8.9, we summarize XVCL commands in a more formal and systematic way.
