| 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.
