Kenn,

Thanks for the prompt reply again, i thought the same.
Is it possible to use the FeatureMap ? I read a tutorial about FeatureMaps
As you said  when call getFA() on an instance of ARModel you'll only

If Ar::fa is a derived feature from ownedMembers will it work , or is there 
a way
we could use dervied features to get both <stereotyped FA > and FA..!!

Thanks,
Saurabh
