40/**
41 * The ServerAttribute class models attributes on the server side.
42 * The primary difference is that values substitute AttributeString
43 * objects for String objects, so attributes compare according to the
44 * rules of SLP matching rather than by string equality. Also,
45 * an AttributeString object for the id is included, for pattern
46 * matching against the id.
