Abstract Validation framework to Actions framework.
---------------------------------------------------

                 Key: VALIDATOR-237
                 URL: https://issues.apache.org/jira/browse/VALIDATOR-237
             Project: Commons Validator
          Issue Type: New Feature
          Components: Framework
    Affects Versions: 1.4
         Environment: All
            Reporter: Bhupesh Naik
            Priority: Minor


Apache Commons validator can be ABSTRACTED to a common framework called ACTIONS framework.
 
The Actions framework will act in similar manner as validation framework but will be independent
of the way in which actions are execute on the value.
 
Abstraction points.
1.Validation can be treated as any action
2.The value to be validated is treated as source value
3.The return value true/false can be treated as a target value
4.Source Value ---pass to--- > list of actions to be executed ----results in---> Target
Value
 
We have already done this in our enterprise product, we use apache validation framework even
for transforming values in our custom ETL framework.
 
Once the apache validator is abstracted as actions framework one can use the same to not only
validate the source value but to transform the value or even in describing and modifying styles
of controls in UI and much more. The advantage here is we use the same digester , loading
of elements, extending forms and stuff, this code remains common.
