31 * An Attribute whose values are relations of a value and a scope.
33 * <p>In practice, scoped attributes are simple pairs of strings instead
34 * of a single string. They can be expressed as a string easily using a delimeter,
35 * typically an '@' symbol. The scope concept allows certain kinds of filtering to
36 * be performed more intelligently and efficiently, although not all scoped
37 * attributes can be effectively filtered (e.g. if the set of scope values is
40 class SHIBSP_API ScopedAttribute : public Attribute
46 * @param id Attribute identifier
48 ScopedAttribute(const char* id) : Attribute(id) {}
50 virtual ~ScopedAttribute() {}
53 * Returns the set of values encoded as UTF-8 strings.
55 * <p>Each compound value is a pair containing the simple value and the scope.
