* Validates a node that is not a class node.

* constraints defined in a {@link MetadataInterface} container

*
|
|
* In both cases, the value is validated against all constraints defined
|
|
* in the passed metadata object. Then, if the value is an instance of
|
|
* {@link \Traversable} and the selected traversal strategy permits it,
|
|
* the value is traversed and each nested object validated against its own
|
|
* constraints. Arrays are always traversed.
