	// for a detailed list of properties.
	// id - String, id of object in dom
	// flashVars - Object, key value pairs representing the flashVars
	// width - Number, width of object.
	// height - Number, height of object.
	// classid - String, Defines the classid of Flash Player. This identifies 
	//		the ActiveX control for the browser. Defaults to "clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
	// codebase - String, Identifies the location of Flash Player ActiveX 
	//		control so that the browser can download it if it is not already installed.
	//		Defaults to "http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,16,0"
	// movie - String, uri of flash swf file
	// align - String, Specifies the position of the SWF file. The align 
	//		property supports the following values:
	//		bottom: Vertically aligns the bottom of the SWF file with the 
	//			current baseline. This is the default value.
    //		middle: Vertically aligns the middle of the SWF file with the
    //			current baseline.
    //		top: Vertically aligns the top of the SWF file with the top 
    //			of the current text line.
    //		left: Horizontally aligns the SWF file to the left margin.
    //		right: Horizontally aligns the SWF file to the right margin.
    //		Defaults to middle
	// allowScriptAccess - String, "always": permits the SWF file to interact with the HTML page in all cases.
	//		"sameDomain": permits the SWF file to interact with the HTML page only when their domains 
	//			match exactly. By default, the HTML publish templates in the Adobe Flash authoring application 
	//			output HTML that specifiesAllowScriptAccess="sameDomain", as this is frequently the desired 
	//			security behavior. 
	//		"never": completely prevents the SWF file from interacting with the HTML page.
	// 
	// bgcolor - String, background color in hexadecimal. Default is #ffffff
	// quality - String, Defines the quality of playback in Flash Player. Valid values of quality are low, medium, 
	//		high, autolow, autohigh, and best. The default value is high.
	// scale - String, Defines how the browser fills the screen with the SWF file. The default value is showall. 
	//		Valid values of the scale property are showall, noborder, and exactfit.
	// salign - String, Positions the SWF file within the browser. Valid values are L, T, R, B, TL, TR, BL, and BR.
	//		The default value is TL.
	// wmode - String, Sets the Window Mode property of the SWF file for transparency, layering, and positioning 
	//		in the browser. Valid values of wmode are window, opaque, and transparent. Default is window.
