AC voltage ratings for capacitors

In various circuits intended for use with 230-250 V AC I''ve seen capacitors labelled as "400V" (Examples: 1, 2) When I look at Capacitor specifications, they often give separate AC and DC ratings. For example: X1 440 VAC 1000 VDC X2 350 VAC Y2 400V (but package confusingly marked "Y2 (330V~) X1 (440 V~) ..
