XML table spaces
An XML table space is an implicitly created universal (UTS) table space that stores an XML table.
An XML table space is implicitly created when an XML column is added to a base table. If the base table is partitioned, one partitioned table space exists for each XML column of data. An XML table space is always associated with the table space that contains the logical XML column value. In this context, the table space that contains the table with the XML column is called the base table space.
If the base table is partitioned, one partitioned table space exists for each XML column of data.
