ActionScript 3.0 :: Include Fonts In A SWF?

I would like to include fonts in a SWF that I am building using Flash CS3 and AS 3. I have found lots of examples online that look like
this:

[Embed(source="C:WINDOWSFontsARIAL.TTF",
fontFamily="Arial")]
private var _arial_str:String;

However, the definition of the variable defined below the EMBED tag varies, sometimes its "Class", sometimes its "Font".

In any event, the font is used this way:

mytext.font = "Arial"

The problem is that this does not work for me. I have tried the various types mentioned above for the asset but none makes any difference.

If I embed the font in the library of my project I can access the font this way:

mytext.font = new AvantGarde().fontName;

But when I try this code with the Embed tag I get different errors compile time depending on how I've define the variable.

It appears that the code samples I found are for Flex and not Flash?

I really want to be able to make this work without embedding the fonts in the library.
