ActionScript 3.0 :: Possible To Use Embedded Fonts And CSS?

Using Flash CS3, I have created a class that when called will
1.) Create a Dynamic text field,
2.) Import external HTML into it,
3.) Apply an external CSS style sheet to it, and
4.) Place it on the stage

So far it works great, but now I'd like to be able to specify an embedded font from the css file. I followed the basic procedure for making a library symbol of the font, setting its linkage to Export for Actionscript on the first frame, and gave it a unique name "myFont"

In my style sheet, I tried using:
font-family: "myFont";
or
font-family: myFont;
but neither way seems to work.

I also found numerous tutorials on how to make it work in AS2, but nothing in AS3. When I specify embedFonts=true in the before-mentioned class, it will not display any of the text, though it does draw the box and any image contents from the html file.
