Declarative Services implementation?

[Scott Lewis]

Howdy,

In browsing through the bundles used in the default Karaf config 
(3.0.2), I didn't seem to see an implementation of DS installed by default.

1) Is there a DS implementation as part of one of the existing Karaf 
features?  If so, what feature is that?
2) If there is such a feature, which impl of DS (and impl version and 
spec version) does it use?
3) Is there a location on the karaf website that documents the 
karaf-usable OSGi standardized non-framework services (like DS, RS/RSA, 
HttpService, etc)?

Thanksinadvance,

Scott
