Create local spatial index on range sub-partitions?

Question

Is is possible to create a local spatial index on a table with range sub-partitions? We're trying to do this on a table that contains lots of x,y,z point data.
Trying to do so gives me the error: ORA-29846: cannot create a local domain index on a composite partitioned tableAccording to the spatial documentation:The following restrictions apply to spatial index partitioning:
- The partition key for spatial tables must be a scalar value, and must not be a spatial column.
- Only range partitioning is supported on the underlying table. All other kinds of partitioning are not currently
supported for partitioned spatial indexes.So there is nothing saying it can or can't be done. The examples I've seen in the documentation tend to partition based on a single value and don't use subpartitioning.
Example of what we're trying to do:SQL> SELECT * FROM V$VERSION;

Ok, thanks. That's what we're planning on doing now.
