|
* Symbol space for ID/IDREF.
|
|
*
|
|
* In XJC, the whole ID space is considered to be splitted into
|
|
* one or more "symbol space". For an IDREF to match an ID, we impose
|
|
* additional restriction to the one stated in the XML rec.

* That is, XJC'll require that the IDREF belongs to the same symbol
|

|
|
