2-2.  "Prolongation" (in footbal (the real one) term)
I don't know now ...  
Parameter ? equals-type="pk/all"
For sure I will add the PK class in the DO.  getter only (? the PK
setting is a entity bean responsability).
On my VO stuffs I will not (and can not) take any assumption on how
equals will be implemented.
Agree or too much "power to user" will be confusing ?

That was my impression as well,but I can understand the one of Dmitri
and David also.
