<complexType abstract="true" name="TheFile">
    <sequence>
     <element name="content" nillable="true" type="soapenc:base64Binary"/>
     <element name="contentType" nillable="true" type="soapenc:String"/>
     <element name="filename" nillable="true" type="soapenc:String"/>
     <element name="name" nillable="true" type="soapenc:String"/>
    </sequence>
</complexType>

Which would indicate that it should just be a base64 encoded binary
data.  So this should have worked, right?:

  $content = "hello world";
  $content = base64_encode($content);

A legit option, but not sure I have the expertise to break down the
NuSoap project to this level.

I had this thought, but the traffic is being passed over SSL, so
Ethereal would only see encrypted garbage.

Ironically (or is it coincidentally?) we had the same thought, but we
were hoping to try to find a solution with NuSoap before we rewrite the
client.
