Merging scores from heterogeneous document engines is too hard for DASL
1.0.  You need a lot of statistics about the various collections.  My
reading of the STARTS document is that they never managed to get vendors to
implement the features that would have returned such information.  Seems to
me that trying to codify this in 1.0 i too hard.   

I like your proposal
