I am seeking a high-level XML representation, one that is understandable by a manager and at the same time is sufficiently detailed that it can be executed
That's the holy grail of computer science - ever since COBOL, people have been trying to find a language that was simple enough for managers to understand but precise enough to express all the detail. No-one has succeeded. I don't think it's a language problem; I think it's an abstraction problem. "Managers" want to reason about the process at a level of abstraction that doesn't involve the sordid detail (handling of exception cases, in particular) that's needed to make the process executable.
I remember well a conversation with the marketing manager of a cable TV company, talking about the process for on-boarding new customers. We kept asking "what if" questions, and the manager got quite frustrated: he was only interested in the success case where everything went smoothly, and wanted someone else to worry about what to do when things went wrong. His staff in the call centre were also quite frustrated: 90% of the calls they took were dealing with things that went wrong, and that weren't covered by the process manual.
An executable process needs to deal not just with the things that often go wrong, it needs to deal with all the things that can ever go wrong, and that's a level of detail that most managers simply aren't interested in.
