duplicate element definitions

[mohs8421]

I am currently investigating, whether I can replace the outdated nusoap library with yours.
However I find one thing alarming in my test implementation.
The application is rather large, so there are many functions available to soap, some have the same parameter names.
The generated wsdl looks like this:
<xsd:element name="login" type="xsd:string"/> <xsd:element name="password" type="xsd:string"/> <xsd:element name="login" type="xsd:string"/> <xsd:element name="password" type="xsd:string"/>
So I have elements defined multiple times, hopefully all of them with the same type, so it might not cause a real problem. But it might also mean, that I cannot use this library for my purpose.
Wouldn't it be better to not define simple types on a global level?

What do you mean "global level"?

[mohs8421]

these elements are defined in types, where I would expect complex types to be defined, not elements of complex types

Could you provide some example, how are you generate the code.
Please give a code how you generate a XML. Current output and expected output.

Current output is something like this:

I removed a lot of duplicates and unimportant details for you, just imagine, that this filter_arr example is used by many operations provided, the same goes for the simple element "login"
The code that generates this is translating from the old library I used to yours.
Essentially I create Node elements directly to circumvent going through the parsing process once more.
These are then passed to the parameters and they are passed to the methods, just as the constructor of Method defines.
Example for the "Filter_arr" parts, it looks like this:

$elements[] = new Node('string', 'column', false);
$elements[] = new Node('string', 'value', false);
…
$parameter = new Parameter(new Node($parameter_type, $parameter_name, $is_array, $elements));
// imagine $out_parameter being constructed the same way
$method = new Method($function, $parameters, $out_parameter);
$wsdl_builder->setMethod($method);

What I would expect is not having simple string message parts defined as their own elements, and not to have duplicate definitions.
