Reporting tasks as processor properties

[Russell Bateman]

Reading the docs on Reporting Tasks, it seemed to me that they said that 
hooking (my word) a reporting task up as a property to a processor is 
the preferred way [1]. I wanted to confirm this as I have yet to stumble 
upon a coded reporting task sample that does this (or, should I say, a 
processor that has a reporting task as a property to set à la controller 
service).

I understand controller services, hooking them up, etc., and I can 
easily imagine how to consume a reporting task in similar fashion, but I 
wanted a) to confirm that I'm not crazy and b) feel warm fuzzies that 
this in fact best practice. Also, if you could refer me to a coded 
processor consuming a reporting task from its properties that would make 
me feel even warmer and fuzzier.

Thanks,

Russ
