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.
