Dag H. Wanvik commented on DERBY-6571:
--------------------------------------

I believe the right term is "deferrable constraints". The short hand "deferred 
constraints" really means a "deferrable constraint" that has constraint mode 
"deferred". C.f. this quote from the standard:

{quote}
"Every constraint is either deferrable or non-deferrable. Within an 
SQL-transaction, every constraint has a
constraint mode; if a constraint is non-deferrable, then its constraint mode is 
always immediate; otherwise, it
is either immediate or deferred."
{quote}

Sorry that lack of precision sneaked into the functional specification ;-)
