Relationship roles

Profile verification

• Actor/use-case endpoint roles remain distinct. Include and generalization graphs are acyclic.
• Use cases declare subject references; selected subject frames and ownership agree.
• Include/extend endpoints share a subject; extend targets a declared extension point and has one supported condition form, not conflicting forms.
• Render extend conditions on the connector label; retain subject and extension-point existence checks.
• Version 3 inherits the supported actor/classifier generalization behavior; its shorter catalogue exclusion must not remove working version-2 functionality.
• Reuse the named base machinery while retaining this profile identity, method route, styling scope and exclusions. Renderer reuse does not import unrelated method permissions.

Profile defaults

Explicit file settings override eligible CSS, then these profile defaults and the common standard apply. Unspecified semantic facts remain unspecified.

• Create actor/use case; connect participation/include/extend/generalization; edit author labels.
• Declare subject membership and extension points; bind extend to a target point and one condition form.
