   You  already  pointed  me to that long ago. Surely, something   the like would be what to use in this case.

   It's not that I totally want to forget about  it.  It's  just   that  I  think  with 7 days left until BETA I better
starton   stressing the code and providing some docs instead of  taking   care for possible abuse.
 
   There  are  details that MUST be documented IMHO. For example   FOREIGN KEY needs that there is a UNIQUE  constraint
defined   on  the  set of referenced columns. Actually this requirement   is not checked in any way, so it MUST  be
mentioned in  the   docs.
