ABSTRACT
How Selectors How selectors are intermediate Web pages between the activity’s highlevel step verbs and the how-to procedures. How selectors also exist for asynchronous event-based procedures. In general, I do not allow a direct reference to any how-to procedure without going through a how selector. This is the software process model mechanism where we achieve extensibility and flexibility at the how-to level. Procedural how-to process elements require a “what” to exist. The “what” options can be:
Any high-level “what” step verb inside an activity that has a howto connection.
