I totally agree. Subentry should be seen as filters, instead of 
implemented the way it is. I like to see them as 'layers' applied on top 
of the Dit. They have the same structure than the Dit, but they restrict 
the number of element you can "see" (in this case, "restrict" means 
applies a set of ACIs). SO when processing an operation, you add the 
subentry filters on the result, or even better, you use the subentry as 
a filter to limit the number of returned elements. Then you don't need 
to modify all the entries the way we do. I don't know if I explain 
corectly what I have in mind, but anyway...
