          - PersonService: Lucene removal
          - Lucene optimizations (in progress)
          - Multi-valued and locale-specific properties persisted in alf_node_properties
          - Removal of unused AVM tables
   10987: Oracle dialects and enhanced SQL patch support
          - Only support Alfresco's 9i and 10g dialects (with auto-switching)
          - SQL script patches can now apply selectively to ranges
   11007: Test to check cached retrieval of QNames
