possible new wsdl element causing validation errors?

hello all,

so i was updating the wsdl for my company's website and ended up getting this error whenever i tried to clear the object cache or access the salesforce api in any way:

( ! ) Fatal error: SOAP-ERROR: Parsing WSDL: Unexpected WSDL element

after some digging around i saw that the structure for the wsdl was this:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="urn:enterprise.soap.sforce.com" xmlns:fns="urn:fault.enterprise.soap.sforce.com" xmlns:ens="urn:sobject.enterprise.soap.sforce.com" targetNamespace="urn:enterprise.soap.sforce.com">
    <types>
      blahblahblah...
    </types><style />

    <!-- Header Message -->
    <message name="Header">
      blahblahblah...
    </message>

    more <message> elements...

    <!-- Soap PortType -->
    <portType name="Soap">
      blahblahblah...
    </portType>

    <!-- Soap Binding -->
    <binding name="SoapBinding" type="tns:Soap">
      blahblahblah...
    </binding>
    
    <!-- Soap Service Endpoint -->
    <service name="SforceService">
        <documentation>Sforce SOAP API</documentation>
        <port binding="tns:SoapBinding" name="Soap">
            <soap:address location="https://login.salesforce.com/services/Soap/c/19.0/0DF70000000L3Zu" />
        </port>
    </service>
</definitions>

instead of this:

<definitions targetNamespace="urn:enterprise.soap.sforce.com"
             xmlns="http://schemas.xmlsoap.org/wsdl/"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"
             xmlns:tns="urn:enterprise.soap.sforce.com"
             xmlns:fns="urn:fault.enterprise.soap.sforce.com"
             xmlns:ens="urn:sobject.enterprise.soap.sforce.com"> 
    <types> 
      blahblahblah...
    </types> 
 
    <!-- Header Message --> 
    <message name="Header"> 
      blahblahblah...
    </message>

    more <message> elements...

    <!-- Soap PortType --> 
    <portType name="Soap"> 
      blahblahblah...
    </portType> 
 
    <!-- Soap Binding --> 
    <binding name="SoapBinding" type="tns:Soap"> 
      blahblahblah...
    </binding> 
 
    <!-- Soap Service Endpoint --> 
    <service name="SforceService"> 
        <documentation>Sforce SOAP API</documentation> 
        <port binding="tns:SoapBinding" name="Soap"> 
            <soap:address location="https://www.salesforce.com/services/Soap/c/18.0/0DF70000000L3Z6"/> 
        </port> 
    </service> 
</definitions> 

In other words, aside from the different SOAP binding (host and version), there is this extra <styles/> element.

Has anyone else run into this with new wsdls? Does anyone know offhand where that element is coming from? And is this a bug in sf or a bug in the module?

As a quick workaround, removing that element seems to make the module work ok again.
