I read "should" as a bit stronger than a recommendation only, but who knows:
1.B.3 Accrual account SHOULD be used for dividends (as of the ex-dividend date).

cfa.teme has it right. when a stock trades ex, the px drops by the dividend. that divi is owed to a long holder, it's like a receivable that *should* be accrued starting on ex date until payable. if anyone else stumbles on the wording again, keep posting it here. FI is for sure accrual, equity then is a "should"... umm, yeah. it's so clear now.
