-- Title:      Pull MLText Values into Node Properties 
-- Database:   Oracle
-- Since:      V2.2 Schema 90
-- Author:     Derek Hulley
--
-- MLText values must be pulled back from attributes into localizable properties.
-- Several statements are not relevant to upgrades from below 77.  These are optional.
