The only idea I have is to make dlgType a two-SQL-boxes dialog and
modify the dlgProperty::apply() method so that if there is "ALTER TYPE
... ADD {BEFORE | AFTER}" statements, they get splitted and fired
individualy. I didn't yet write the code to split the statement, but it
will surely be ugly.

Any objection on doing this? or better idea to fix this issue?
