39 * Reference to other schema components. |

|
41 * <p> |
|
42 * There are mainly two different types of references. One is |
|
43 * the direct reference, which is only possible when schema components |
|
44 * are already available when references are made. |
|
45 * The other is the lazy reference, which keeps references by names |
|
46 * and later look for the component by name. |
|
47 * |
|
48 * <p> |
|
49 * This class defines interfaces that define the behavior of such |
|
50 * references and classes that implement direct reference semantics. |
