Name Type Mult. Description Owning Classifier
available Boolean 0..1

Defines whether the cavity is available for contacting. If the cavity is not available, it means that it is completely closed.

cavityNumber String 0..1

Provides an identifier for the cavity. The cavity number needs to be unique within a Slot.

hasIntegratedTerminal Boolean 0..1

Defines whether the cavity has an integrated terminal (for example an IDC cavity) or if an additional terminal is required.

If this attribute is "true", the cavity can reference a TerminalSpecification as integratedTerminalSpecification in order to specify the integrated terminal.
