dbms_lobutil contains diagnostic and utility functions for 11g LOBs.
The API that is exposed through dbms_lobutil, or its underlying data structures, are subject to possibly backwards-incompatible changes.
The diagnostic API offered in dbms_lobutil are provided separately from dbms_lob to avoid clutter.
Because this diagnostic API is intended for (Oracle-) internal developers, QA and DDR, Oracle does not seem to document this API for end-users
