Well you could ask them what the following hexa values stand for in the trace files

Code:
/* 0x01 = typed table, 0x02 = has ADT columns, */
/* 0x04 = has nested-TABLE columns, 0x08 = has REF columns, */
/* 0x10 = has array columns, 0x20 = partitioned table, */
/* 0x40 = index-only table (IOT), 0x80 = IOT w/ row OVerflow, */
/* 0x100 = IOT w/ row CLustering, 0x200 = IOT OVeRflow segment, */
/* 0x400 = clustered table, 0x800 = has internal LOB columns, */
/* 0x1000 = has primary key-based OID$ column, 0x2000 = nested table */
/* 0x4000 = View is Read Only, 0x8000 = has FILE columns */
