 From a pure framework perspective I'm totally in agreement with the 
above (irrespective of the pain and suffering I'm enduring with respect 
to the metainfo/metadata issues inflicted by an unmentionable 
"Australia" personality).  However, if we take into account ECM and the 
interest in facilitating a smooth migration path, I see only two 
alternative; either we provide a lookup( role, hint) in the framework 
(which I dislike in terms of the curent form being dicusssed), or (b) an 
extended CM is defintion at the excalibur level that provide a bridge 
from ECM to the emerging container models.

Cheers, Steve.
