/**
* A violation of a constraint that happened during validation.
*
* For each constraint that fails during validation one or more violations are
* created. The violations store the violation message, the path to the failing
* element in the validation graph and the root element that was originally
* passed to the validator. For example, take the following graph:
*
* <pre>
* (Person)---(firstName: string)
* \
* (address: Address)---(street: string)
* </pre>
*
* If the <tt>Person</tt> object is validated and validation fails for the
* "firstName" property, the generated violation has the <tt>Person</tt>
* instance as root and the property path "firstName". If validation fails
* for the "street" property of the related <tt>Address</tt> instance, the root
* element is still the person, but the property path is "address.street".
