Use XML and other proper AS3 classes instead of the legacy XMLNode and such
Description
"The XMLNode class represents the legacy XML object that was present in ActionScript 2.0 and that was renamed in ActionScript 3.0. In ActionScript 3.0, consider using the new top-level XML class and related classes instead, which support E4X (ECMAScript for XML). The XMLNode class is present for backward compatibility."
XIFF uses heavily XMLNode. Migrate to XML and XMLList.
