PHP SOAP server for SAP client has configuration issues in WSDL

I've coded a WS SOAP server using NuSOAP library, and it's working pretty fine, but as the client should be a SAP implementation, there are some issues when trying to reach it from SAP.

My WSDL is automatically generated by nusoap contains following definitions

<definitions targetNamespace="https://example.com/ws/" 
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 
    xmlns:tns="https://example.com/ws/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/">
    <types>
        <xsd:schema elementFormDefault="qualified" targetNamespace="https://example.com/ws/">
        <xsd:import namespace="http://schemas.xmlsoap.org/soap/encoding/"/>
        <xsd:import namespace="http://schemas.xmlsoap.org/wsdl/"/>

This WSDL is validated by soap-ui 5.5 and it works fine with php clients, but not with SAP.

At first time I must switch from rpc/encoding style to document/literal and I can achieve it changing some configurations values in nusoap server class.

Anyway there is a remaining issue according to SAP diagnostics and it is fired by <xsd:import namespace="http://schemas.xmlsoap.org/soap/encoding/"/>.

The error in SAP is

Incorrect value: Unknown namespace http://schemas.xmlsoap.org/soap/encoding/

I've tested that URL and is correct.

Also I'm trying to strip out that line from soap server class without success, because I found it and commented at line 1106 in class.soap_server.php:

$this->wsdl->schemas[$schemaTargetNamespace][0]->imports['http://schemas.xmlsoap.org/soap/encoding/'][0] = array('location' => '', 'loaded' => true);

But it doesn't have any effect in generated WSDL.

Any idea will be really appreciated. Thank you in advance.

SAP doesn't support RPC-style in Web-services, hence the error.

Here the SAP note which explains how to adapt it

I attach samples which explaining WSDL format which are contained in the note in case you do not have S-login to access the note.
