>             Project: Felix
>          Issue Type: New Feature
>          Components: iPOJO
>    Affects Versions: ipojo-runtime-1.10
>            Reporter: Clement Escoffier
>            Assignee: Clement Escoffier
>             Fix For: ipojo-runtime-1.10.1
> When iPOJO is tracking services, it should let extenral entities to intercept service
resolution to determine the services to use.
> With this feature it is possible to:
> * mark services
> * change filters, even build filter chains
> * update the selected services dynamically
> Two interception are supported:
> * tracking : allow filtering out and transforming references. Transformation changes
the properties of the reference
> * ranking : sort the set of references
> Both interceptors are exposed as services and are plugged on the service dependency dynamically.
Obviously they can leave and arrive at runtime. To manage a dependency, they expose a service
property named 'target' which is a LDAP filter selecting a set of dependencies.
