I was told once that it stands for "working voltage"; at least, that''s what the photo flash community transports. So, it''s the same: a voltage rating. For guarantees made when using that voltage or below, you''ll have to read the datasheet for the individual capacitor, anyways, so your question is (and I mean this positively) kind of pointless:
The DC working voltage is the maximum DC voltage and NOT the maximum AC voltage. A capacitor with a DC voltage rating of 100 volts DC cannot be safely used to an AC voltage of 100 volts. This is because an alternating voltage that has an RMS value of 100 volts will have a peak value over 141 volts (√2 x 100). So, a capacitor that is required ...
