2 - Unexpected event, expected end-tag error when wsdl:portType appears between wsdl:message elements

[define-null]

While trying to generate erlang modules from wsdl faced with the following scenario:

<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" targetNamespace="example.com/contacts">
    <wsdl:types>
        <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="example.com/contacts" elementFormDefault="qualified" attributeFormDefault="unqualified">
            <xsd:element xmlns:tns="example.com/contacts" name="contacts_response" type="tns:contacts_response"/>
            <xsd:element xmlns:tns="example.com/contacts" name="person" type="tns:person"/>
            <xsd:complexType name="contacts_response">
                <xsd:sequence>
                    <xsd:element name="result" type="xsd:string"/>
                </xsd:sequence>
            </xsd:complexType>
            <xsd:complexType name="person">
                <xsd:sequence>
                    <xsd:element name="first_name" type="xsd:string" minOccurs="0"/>
                </xsd:sequence>
                <xsd:attribute name="id" type="xsd:integer"/>
            </xsd:complexType>
        </xsd:schema>
    </wsdl:types>

    <wsdl:message name="contacts_responseOut">
        <wsdl:part xmlns:tns="example.com/contacts" name="parameters" element="tns:contacts_response"/>
    </wsdl:message>

   <wsdl:portType name="contactsPortType">
        <wsdl:operation name="store">
            <wsdl:input xmlns:tns="example.com/contacts" message="tns:personIn"/>
            <wsdl:output xmlns:tns="example.com/contacts" message="tns:contacts_responseOut"/>
        </wsdl:operation>
    </wsdl:portType>

    <wsdl:message name="personIn">
        <wsdl:part xmlns:tns="example.com/contacts" name="parameters" element="tns:person"/>
    </wsdl:message>

    <wsdl:binding xmlns:tns="example.com/contacts" name="contactsBinding" type="tns:contactsPortType">
        <soap:binding xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" transport="http://schemas.xmlsoap.org/soap/http"/>
        <wsdl:operation name="store">
            <soap:operation xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" soapAction="store" style="document"/>
            <wsdl:input>
                <soap:body xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" use="literal"/>
            </wsdl:input>
            <wsdl:output>
                <soap:body xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" use="literal"/>

What must be generated?

2: server
3: both
Select a number: 1

Do you want to generate test stubs/skeletons?
1: no
2: yes, client only
3: yes, server only
4: yes, client and server
Select a number: 1

Which http client must be used?
1: ibrowse
2: inets
Select a number: 1
** exception error: no match of right hand side value {error,[{exception,{error,{"2 - Unexpected event, expected end-tag"}}},
                                                              {stack,['wsdl:definitions']},
                                                              {received,{startElement,"http://schemas.xmlsoap.org/wsdl/",
                                                                                      "message","wsdl",
                                                                                      [{attribute,"name",[],[],"personIn"}]}}]}
     in function  soap_parse_wsdl:get_services/3 (src/soap_parse_wsdl.erl, line 104)
     in call from soap:wsdl2erlang/2 (src/soap.erl, line 305)

Moving wsdl:portType below all wsdl:message elements solve the issue.
But I don't see any order specification in the wsdl schema, so guess it's potentially a bug in soap model.

@willemdj any thoughts on this?
