Is Executable UML a standard?
Yes and No. The notational elements you see in this book conform to UML, and so qualify as a profile of that standard. In addition, the execution semantics defined here conform to UML, though we do both subset UML and impose certain rules to link the elements together. What is not yet a standard is the exact content of what can and should be interchanged so that we can guarantee that any and all model compilers, irrespective of vendor, can compile any arbitrary executable UML model. Throughout this book, we use standards as much as they are established. In some areas, the book is intended to provide a basis for discussion of what should ultimately become a standard.
