But, how would you write a ServiceTracker do track it?

I need a tracker to get the DS components to collaborate with a non-DS
system.

i.e. the target isn't a component using a @Reference annotation. It's a
pure service tracker.

I'm trying to implement a generic mechanism that allows annotation classes
with an existing web service annotation. When such a class is registered as
a service (in this case using DS annotations), I would like to register it
in our existing web service framework.

These web services don't "infer" any particular type, other than the web
service annotation.
