/**
* Provides a wrapper to namespace a resource.
*
* {@link NamespaceableResource} is not {@link Namespaceable} to allow for future versions of the logic
* to be consolidated.
*
* With generic typed interface design Namespacable<X> and Namespaceable<Y> are considered incompatible no matter
* the types for X and Y,
* but NamespaceableX and NamespaceableY can be polymorphic. As long as there is no usage expectation
* like instanceof Namespaceable - then it would be fine to have the non-generic versions.
*
* The constructor and the inNamespace method determine the namespacing rules:
* - if the item is namespaced, the resource context will use that namespace as that is not currently the default behavior of
* withItem
