    having personally struggled with the general usage of the term 'target' 
    in the past, i too am comfortable with the concept of 'Target Values' 
    and 'Target Mapping' as defined by hal's previous note.
    
    i also agree with tim's assertion that policies should map to fully 
    qualified namespaces. i think that this will be necessary to maintain 
    any hopes of interoperability.
