[flexcoders] soap-env Namespace problem

[Shannon]

This code works just fine:

var envelope:XML = <soap-env:Envelope
xmlns:tpro="http://aplaud.com/ns/0.1/tts/profile";
xmlns:tf="http://aplaud.com/ns/0.1/tts/format";
xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/";>
<soap-env:Header>{SomeHeadXML}</soap-env:Header>
<soap-env:Body>{SomeBodyStuff}</soap-env:Body>
</soap-env:Envelope>;
var url:String = "http://my_domain/bleh.php";;
var callback:Function = handleBlehResponse;
ur.method = URLRequestMethod.POST;
ur.url = url;
ur.data = envelope;                     
ur.requestHeaders.push(RH);
var ul:URLLoader = new URLLoader(ur);
ul.addEventListener(Event.COMPLETE,callback);
ul.load(ur);

But I have many of these to write so I would like to place the soap-
env in a CONSTANT (in the super) and add HEADER and BODY nodes later. 

Something like this...

static public var ENVELOPE:XML = <soap-env:Envelope
xmlns:tpro="http://aplaud.com/ns/0.1/tts/profile";
xmlns:tf="http://aplaud.com/ns/0.1/tts/format";
xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/";>
<soap-env:Header></soap-env:Header>
<soap-env:Body></soap-env:Body>
</soap-env:Envelope>;

var env = new XML(ENVELOPE.toString());
var soap-env:Namespace = new Namespace
("http://schemas.xmlsoap.org/soap/envelope/";);
env::soap-env.Header = SomeHeadStuff;
env::soap-env.Body = SomeBodyStuff;


I think the trouble is with namespaces, but I have no idea how to 
specify a hyphenated namespace "soap-env" or if I even need to.

TIA
