## Discussion

This attribute’s value must be one of the constants listed below that indicate the alignment in the writing direction of the first line of text of the cue. The value (or absence) of the [`kCMTextMarkupAttribute_VerticalLayout`](/documentation/CoreMedia/kCMTextMarkupAttribute_VerticalLayout) attribute indicates the writing direction. The default value of this attribute is [`kCMTextMarkupAlignmentType_Middle`](/documentation/CoreMedia/kCMTextMarkupAlignmentType_Middle).

If you use this attribute, apply it to the entire attributed string.
