remarks

the sub and super values are supported on text. the auto value is supported on the currentstyle object. the other values are supported on objects that support valign.

the auto value is identical to the baseline value when the layout-flow is horizontal. when the layout-flow is vertical-ideographic, the auto value is identical to the middle value.
