Remarks
The starting point of the curve may be identified in absolute output coordinate terms
using
the x and y attributes or relative to the location of another element
using the startid attribute. The attributes in the att.visualOffset class may be
used to record horizontal, vertical, or time offsets from the absolute coordinates
or from

may be
recorded using either the x2 and y2 coordinates or in relation to the

att.visualOffset2 class maybe used to record the offsets of the ending point. The
bulge attribute or, alternatively, the bezier attribute, describe the
