/**
* 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
* space as the ID. Having this concept allows us to assign more
* specific type to IDREF.
*
*
* See the design document for detail.
