When launching Stduio, and creating a new schema project, we can select the ADS schema. The one that are loaded are a ADS 1.5.3 version, where some OC are missing.
For instance, the following apache schema OC :
objectclass ( 22.214.171.124.4.1.18060.0.4.1.3.12
DESC 'represents change events'
MUST ( changeTime $ changeType $ rev $ committer ) )
objectclass ( 126.96.36.199.4.1.18060.0.4.1.3.13
DESC 'represents a Tag in change log'
MUST ( rev )
MAY ( description ) )
are missing (they have been added in december 2008
