Bug Report

Q	A
BC Break	no
Version	1.8.0

Summary

See phpro/soap-client#517
WSDL: axlsqltoolkit.zip

The cisco AXL WSDL contains:

<definitions 
	xmlns="http://schemas.xmlsoap.org/wsdl/" 
	...>
	<import location="AXLSoap.xsd" namespace="http://www.cisco.com/AXL/API/15.0"/>
</definitiions>	

Current behaviour

The flattening process results in:

<definitions 
	xmlns="http://schemas.xmlsoap.org/wsdl/" 
	...>

	XSD CONTENT

        <types/>
</definitiions>	

Expected behaviour

<definitions 
	xmlns="http://schemas.xmlsoap.org/wsdl/" 
	...>
        <types>
         	XSD CONTENT
        </types>
</definitiions>
