[PDF/Javascript] Adding multiline rich text

var annot = this.addAnnot({
	page: 0,
	type: "Text",
	point: [72,500],
	popupRect: [72, 500,6*72,500-2*72],
	popupOpen: true,
	noteIcon: "Help"
});

var spans = new Array();
spans[0] = new Object();
spans[0].text = "Attention:\r";
spans[0].textColor = color.blue;
spans[0].textSize = 18;

spans[1] = new Object();
spans[1].text = "Adobe Acrobat 6.0\r";
spans[1].textColor = color.red;
spans[1].textSize = 20;
spans[1].alignment = "center";

spans[2] = new Object();
spans[2].text = "will soon be here!";
spans[2].textColor = color.green;
spans[2].fontStyle = "italic";
spans[2].underline = true;
spans[2].alignment = "right";

// Now give the rich field a rich value
annot.richContents = spans;
