Specifying arguments to Webservice calls

Question

I have the following code:
Sample Code is:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:WebService id="wsTest" wsdl="
http://192.168.1.108:8080/stockquotes/stock_quote?wsdl"
useProxy="false">
<mx:operation name="sendStrings">
<mx:request xmlns="">
<arg0>One</arg0>
<arg0>Two</arg0>
<arg0>Three</arg0>
</mx:request>
</mx:operation>
</mx:WebService>
<mx:VBox x="38" y="10" height="287" width="297"
id="btSend">
<mx:Button label="Send Many Strings"
mouseDown="wsTest.sendStrings.send()"/>
</mx:VBox>
</mx:Application>
If I try to send a parameter to a web service function that
takes an array of parameters (arg0 elements), than flex generates a
fault (Unexpected parameter 'arg0' found in input arguments) before
it even attempts to communicate with the webservice. If I try to
send a single arg0 element, I still get the error.
The specification for the input parameters is
<xs:complexType name="sendStrings">
<xs:sequence>
<xs:element name="arg0" type="xs:string"
maxOccurs="unbounded" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
So, apparently I don't know how, nor can I find in the docs,
how I would specify that the input is an array. I tried wrapping my
element, but that faults in the same way because it didn't
recognize the parameter name. I even tried defining the xs
namespace and wrapping my array in an xs:sequence element.
Any idea how I can specify a parameter which is an array?
Thanks.

Thanks for the reply. I have been running tcpdump on the
server and can see that no data has been sent to the server.
However, I tried that anyway and found out that it doesn't
make it to the invoke event when I try to send across an array. It
does when I send across a single parameter, so I know it's working.
I'm not sure what Flex thinks the name of the parameter
really is. I have tried everything that I can think of and it still
doesn't work.
Any ideas?
Thanks.
