Description

assume the following scenario:

• mixin A declares the mandatory property p
• mixin A' extends from A
• node n has mixin A'
• we'd like to migrate/downgrade node n from mixin A' to A

currently there's no easy way of replacing the assigned mixins.

assigning A first results in a NOP since A would be redundant.
removing A' first removes the mandatory property p.

a new method setMixins(String[]) would allow to migrate
a node from mixin A' to A while preserving 'shared' content.
the semantics of setMixins(String[]) would be similar to
Node.setPrimaryType(String).
