UML22 — issue regarding required and provided interfaces

There appears to be an issue with required and provided interfaces of Components in the UML2 Super Structure specification 2006-04-02 section 8.3.1., p.151 .

In the OCL and the paragraph discussing required and provided interfaces there is no mention of inheriting provided or required interfaces from the supertypes of the component.
Should we also consider required or provided interfaces of inherited ports?
Should we also consider supertypes of realizing classifiers?

The fact that Components don't consider supertypes is contrary to how Ports get required and provided interfaces on p187. Ports consider supertypes of the classifiers that type them when collecting required and provided interfaces.
