How to embed TEXT or XML in AS

We have possibility to embed XML via MXML Tag

<mx:XML id="xxx" source="/xml.xml" />

.
Question: How can we do the same in AS?
Answer: "The same" - noway, but we can do this "much as the same"

/**
*  Parse embedded data as String:
*  [Embed(source="/text.txt", mimeType="application/octet-stream")]
*  private static const embeddedData:Class;
*/
public static function getEmbeddedString(embedApplicationOctetStreamData:Class):String
{
    var embedData:ByteArrayAsset = ByteArrayAsset(new embedApplicationOctetStreamData());
    return embedData.readUTFBytes(embedData.length);
}

/**
*  Parse embedded data as XML file:
*  [Embed(source="/xml.xml", mimeType="application/octet-stream")]
*  private static const embeddedData:Class;
*/
public static function getEmbeddedXML(embedApplicationOctetStreamData:Class):XML
{
    var embedData:ByteArrayAsset = ByteArrayAsset(new embedApplicationOctetStreamData());
    return new XML(embedData.readUTFBytes(embedData.length));
}
