With the 'freshens' and 'supplements' dependencies.

'Freshens' acts like a condition. If the frehens dependency is fulfilled 
(package/pattern
being installed or to-be-installed), the supplements dependency is evaluated.
So in the above example, Konversation would freshen the KDE pattern.

Yes. But dependencies are only possible from the higher to an equal
or lower abstraction level.
So a pattern can only depend on another pattern or a package. But
a package cannot depend on a pattern.
