2006/06/27 13:56:11 fs 1.7.104.3: RESYNC: (1.7-1.8); FILE MERGED
2006/06/16 11:32:29 fs 1.7.104.2: during #i51143#:

refactored VCollection:
- createEmptyObject now named createDescriptor
- cloneObject removed
- appendObject now returns the newly created object
  (previously done via a subsequent call to cloneObject)
2006/05/23 13:24:21 fs 1.7.104.1: some refactoring of compose/quoteTableName and friends, in preparation of #i51143#
