/**
* Specifies whether an object should be cascaded.
*
* Cascading is relevant for any node type but class nodes. If such a node
* contains an object of value, and if cascading is enabled, then the node
* traverser will try to find class metadata for that object and validate the
* object against that metadata.
*
* If no metadata is found for a cascaded object, and if that object implements
* {@link \Traversable}, the node traverser will iterate over the object and
* cascade each object or collection contained within, unless iteration is
* prohibited by the specified {@link TraversalStrategy}.
*
* Although the constants currently represent a boolean switch, they are
* implemented as bit mask in order to allow future extensions.
