== Declaring additional capabilities for a local component

All components have an _implicit capability_ corresponding to the same GAV coordinates as the component.
However, it is also possible to declare additional _explicit capabilities_ for a component.
This is convenient whenever a library published at different GAV coordinates is an _alternate implementation_ of the same API:
