-           Note that Regions in WebVTT cannot be moved at this time, so if there is a need to move to a different on-screen location, because a different PAC row number is given, it is best to define another Region for that location and copy the caption text. Such a region move happens only if the base row of the PAC of a caption is different from the previous caption's PAC base row. A different PAC indent can be dealt with within the existing region by simply applying the indent as a position indent to the caption cue as described in the section on "Positioning in CEA-608".
