    > What do you mean by that? There is no bean name.
    
    Users may set `class` attribute to a 1.class name or to a 2.bean name. I meant I think
it is not nice to use `class` attribute for, as you say, two different topics. Additionally,
in second use, S2 cannot know the config time class of the action in any clean way.
    
    > every action
    
    Not every. `bean` attribute is and will be optional. Just actions which their `class`
attribute value can not be resolved to config time class of the action by `ojectfactory.getInstanceClass`.
For example `<action class=beanName` with `<bean name=beanName class=com....` and if
this bean is proxified e.g. by AOP needs to be protected. This PR warns about these and continue.
    
    > It is not about the amount of changes
    
    Sorry I meant about docs, satisfying user with the new design or param and maintain it
for log time.
    
    > Yet another is to compare action configuration class with the current instance toString
/ getClass().toString
    
    As I mentioned, when user uses `class` attribute as a bean name, S2 cannot know the action
configuration class in any clean way.
    
    > You're mixing two very different topics together, security and chain configuration.
    
    No, I think about S2 borders. I'm trying to discuss that S2 should or should not know
the config time class of the action and then do not operate outside of that border. Input
Parameters, Chain and JSON are three example operations of S2 which I discovered at first
place. Then I discovered `<s:form validate=true`. I see all of these are because S2 1.does
not know and 2.do not consider config time class of the action.
