For literals, yes, we’d for the most part just pass the whole thing as a string
to the constructor. The only exception I can think of is bracket notation:
var foo:XML = <node><subnode attr={myAttr}>foo</subnode></node>;
would have to become:
var foo:XML = new XML('<node><subnode attr="‘+myAttr+’">foo</subnode></node>’);
Wrapping the xml in a dummy node is a good idea. I like that. Thanks!
