[Xml-compile] Enforcing encodingStyle attribute?

Juk!  I disgust RPC-style.

You only need one WSDL11 object per program.

It should select that automatically.  (I speak/understand German, but
don't ask me to write it)

The SOAP11 schema explicitly forbids this "encodingStyle" attribute:

  <xs:element name="Envelope" type="tns:Envelope"/>
  <xs:complexType name="Envelope">
    <xs:sequence>...</xs:sequence>
    <xs:anyAttribute namespace="##other" processContents="lax"/>
  </xs:complexType>

Also, you specify the SOAP1.1 namespace as encodingStyle, which is
definitively incorrect.

I think there is something else which troubles this.  My RPC support
is a but shaky: gladly nearly no-one uses that anymore.

If you can send me a small script which demonstrates your problem, I'll
have a look at it.
