Juergen,
You have described a Task registry on several occasions, but we have no
details in writing or examples in the Framework RFC because this registry
concept is new.

Now that the information model has been generalized to allow for a Task 
registry, I want to understand how you intend to use that registry
and how it interacts with the Metrics registry (whose role we have 
understood for years, but now potentially changes, I cannot tell how).

Phil and I have both asked for examples so that we can understand 
the implications of the changes you've executed. Examples have been
the stepping stones to reach greater clarity in much of our work in
LMAP over the last year, and I provided quite a few examples for the 
metrics registry and Cycle Number discussions.

Help us understand how you think LMAP will work now,
Al
