Alan I am not sure.
If I understand sql:2003 spec. correctly, then order shall be :
(If we suppose, that referential constraint is IMMEDIATE and triggers
are FOR EACH ROW ... which is case of Firebird, as I think.)

1. Befor master trigger
2. referential constraint (if their <constraint check time> is
IMMEDIATE, which is default) are procesed ...
2.1 Before delete detail
2.2 After delete detail
3. After delete master

hm ?
