Contains the x- and y-coordinates of the first vertex of a shape, or contains the x- and y-coordinates of the first vertex after a break in a path.Coordinates are specified as relative coordinates.
X element represents the x-coordinate of the first vertex of a path. If the MoveTo element appears between two elements, the X element represents the x-coordinate of the first vertex after the break in the path
Y element represents the y-coordinate of the first vertex of a path. If the MoveTo element appears between two elements, the Y element represents the y-coordinate of the first vertex after the break in the path.
