aoqi@0 | 32 | * Symbol space for ID/IDREF. |
aoqi@0 | 33 | * |
aoqi@0 | 34 | * In XJC, the whole ID space is considered to be splitted into |
aoqi@0 | 35 | * one or more "symbol space". For an IDREF to match an ID, we impose |
aoqi@0 | 36 | * additional restriction to the one stated in the XML rec. |
aoqi@0 | 37 | * |
aoqi@0 | 38 | * <p> |
aoqi@0 | 39 | * That is, XJC'll require that the IDREF belongs to the same symbol |
aoqi@0 | 40 | * space as the ID. Having this concept allows us to assign more |
aoqi@0 | 41 | * specific type to IDREF. |
