^ Name ^ Type ^ Cardinality ^ Description ^
| [[.:compartmentproperties|CompartmentProperties]] | ocx:CompartmentProperties_T | [1, 1] | The physical properties of a compartment volume (COG, air pipe top). |
| [[.:cell|Cell]] | Cell | [1, ∞] | Structural concept of a cell defining a closed volume which is part of a compartment (physical space). |
| [[.:crossflow|CrossFlow]] | CrossFlow | [0, ∞] | Concept to specify cross flow between Cells making up a Compartment. This enables the modelling of cells that are not adjacent but are connected by a piping system and part of the same Compartment. |
| [[.:externalgeometryref|ExternalGeometryRef]] | ocx:ExternalGeometryRef_T | [0, 1] | The ExternalGeometryRef element is used to point to an external geometry representation of the parent entity (e.g. Plate, Stiffener, Bracket, Member). |
| [[.:bulkcargo|BulkCargo]] | ocx:BulkCargo_T | [1, 1] | A bulk cargo is a type of dry cargo that is solid cargo that is not packed, but is carried loose. Ref. is made to ISO 10303-215:2004. |
| [[.:liquidcargo|LiquidCargo]] | ocx:LiquidCargo_T | [1, 1] | Liquid cargo properties, reference is made to ISO 10303-215:2004. A liquid cargo is a type of Cargo whose natural condition is a non-solid, non-gaseous liquid state. |
| [[.:unitcargo|UnitCargo]] | ocx:UnitCargo_T | [1, 1] | The UnitCargo type is intended for spaces carrying a type of dry cargo that that is packed or comprises discrete units that can be loaded and stored individually on the ship. Ref. is made to ISO 10303-215:2004. |
| [[.:description|Description]] | xs:string | [0, 1] | Contains a description of the component its parent represents. The description is stored as a string. You can use this element for whatever purposes you require. This element can be used inside many OCX XML elements but is optional. |
| [[.:customproperties|CustomProperties]] | ocx:CustomProperties_T | [0, 1] | Container for custom properties. |
