This comment may be good or bad for the acceptance of what you are proposing
(given my record of success of the list ;-) ). I am all for something like this.
I would go a step further and also require your dynamic interface to manage
elements (as well as attributes). So the interface would be something like:
interface DynamicConfigurator {
void setDynamicAttribute(String name, String value);
Object createDynamicElement(String name);
}
This will allow writing tasks that have their own dynamic subset of valid
elements, for example <ejb-jar> would not have to be modified every time
a new EJB container is supported, but instead the new plug-in will be declared
in some registry and the task will use createDynamicElement() to search for the
correct
plug-in element to instantiate.
The same is applicable to things like <conditional>, <mappers>, etc.
And it would finally allow to define a real useful <script> like task
in which we can define real useful <ScriptTasks> that can be used
in multiple places with different parameters.
To tell you the truth, the current <script> task is kind of useless in my
opinion.
Hope my comments dont kill your idea ;-)
