Well, the rule is identified to the cursor(s) it should "cover" by the value in the cWorkarea property - "*" for all cursors or a comma delimited list of cursor names.

Well you could use a single rule class for all your rules and apply it to any cursor but this would be somewhat counter productive. You would end up with a potentially massive rule class being added to a CDE that may just have a single cursor. 99% of the rules may not apply to cursors in that particular CDE.

Maybe the best thing to do is to create a smallish number of rule classes that apply to logically related cursors. However, I personally don't find it a hassle creating a single rule class for a new CDE and using the one class to cover all of the cursors in that CDE. I know that the main Codemine idea is creating re-useable rule classes so that you can create one rule, and use it anywhere. Up to now though, I haven't come across a situation where I am using the same data sources in multiple CDE's so, I haven't had a good chance to reuse my rule classes.
