36 * An Attribute whose values are relations of a value and a scope.
38 * <p>In practice, scoped attributes are simple pairs of strings instead
39 * of a single string. They can be expressed as a string easily using a delimeter,
40 * typically an '@' symbol. The scope concept allows certain kinds of filtering to
41 * be performed more intelligently and efficiently, although not all scoped
42 * attributes can be effectively filtered (e.g. if the set of scope values is
