These methods provide support for managing "strategies", i.e.
mixin-classes, where only one kind of a family of conformant
mixins should be registered.
<p>
Naming convertions for strategies:
All strategies must follow the naming convention 'kind=implementation'.
Examples are the persistency strategy 'eager' specfied as
'persistent=eager' or the persistency strategy 'lazy' (specified as
'persistent=lazy')
