Yes.

Here's what von Halle says:

   Business people may not be overly interested
   in data models, process models, or object models.
   But they are definitely interested in business
   policies and rules. Indeed, it is through policies
   and rules that business leaders steer the business.


And she also writes:

   analysts capture the ... rules of the system
   and developers express them as declarative rules
   rather than procedural code.

What category would you place XSLT:

 - A language for expressing process/workflow rules

 - A language for expressing data validation rules

 - A language for expressing user interface rules

 - A language for expressing data relationship rules

Or perhaps another category?


Thanks!
