ConcernUsage SysML

class ConcernUsage

Implementation of ConcernUsage defined in the SysML specification.

Specification:

A ConcernUsage is a Usage of a ConcernDefinition.

The owned_stakeholder features of the ConcernUsage shall all subset the ConcernCheck::concerned_stakeholders feature. If the ConcernUsage is an owned_feature of a StakeholderDefinition or StakeholderUsage, then the ConcernUsage shall have an owned_stakeholder feature that is bound to the self feature of its owner.

For language description, see section 7.21.3 of the SysML specification. For more details on the model, see section 8.3.21.4 of the SysML specification.
