/**
* Allows plugins to decide whether a change is ready to be submitted or not.
*
* For a given {@link ChangeData}, each plugin is called and returns a {@link Collection} of
* {@link SubmitRecord}. This collection can be empty, or contain one or several values.
*
*
A Change can only be submitted if all the plugins give their consent.
*
*
Each {@link SubmitRecord} represents a decision made by the plugin. If the plugin rejects a
* change, it should hold valuable informations to help the end user understand and correct the
* blocking points.
*
*
It should be noted that each plugin can handle rules inheritance.
*
*
This interface should be used to write pre-submit validation rules. This includes both simple
* checks, coded in Java, and more complex fully fledged expression evaluators (think: Prolog,
* JavaCC, or even JavaScript rules).
