- Made LimitedBy optional for Plate. (oca) ``Plate``
- Made LimitedBy optional for Panel. (oca) ``Panel``
- Made the BarSection type abstract. All section types must inherit from the BarSection and are made a global element. This allows to uniformly treat reading and writing of section types. (oca) ``BarSection``

- Removed the ConfigurationRef (reference to other stiffener end configuration) from the Pillar to avoid circular dependency. (oca) ``Pillar``
- Removed the ConfigurationRef (reference to other stiffener end configuration) from the Stiffener to avoid circular dependency. (oca) ``Stiffener``

- Changed HoleRef to OcxItemPtr type. (oca) ``HoleRef``
- Changed CrossSection to SectionRef on the Pillar type. (oca) ``Pillar``
- Changed cardinality of FreeEdgeCurve3D. A FreeEdgeCurve3D need to contain at least one Curve3D, and can be a combination of different unlimited Curve3D types in any sequence. (oca) ``FreeEdgeCurve3D``
- Renamed DEXItemPtr to OcxItemPtr. (oca) ``OcxItemPtr``
- Added enumerator for the bracket position. (oca) ``BracketParameters``

- Changed Schema name space from dex to ocx. (oca) ``ocxXML``
- Made it possible to specify only one Inclination in case of a straight stiffener trace line. (oca) ``Stiffener``
- Removed NurbsSurfaceCollection as this is an unnecessary layer. (oca) ``Surface``

- Made CellConnection a global element. (oca) ``CellConnection``
- Added FreeEdgeCurve3D to the enumeration types. (oca) ``refType``
- Changed from Member to Pillar in the enumeration types. (oca) ``refType``
- A Stiffener may be attached to a Plate, a Pillar or another Stiffener at the configuration position. (oca) ``ConnectionConfiguration``
- A Penetration can either penetrate a Plate, a Pillar or a Stiffener. (oca) ``Penetration``
