Picking up the wrong TargetNamespace

[notzippy]

In my WDSL the schema defines a target name space of

    <xsd:schema elementFormDefault="qualified" targetNamespace="http://purolator.com/pws/datatypes/v1" xmlns:tns="http://purolator.com/pws/datatypes/v1">

and the WSDL target namespace is different

<wsdl:definitions name="ServiceAvailabilityService" targetNamespace="http://purolator.com/pws/service/v1" ...>

When rendering the structure (in GoWsdl.genTypes) the template function targetNamespace returns the wsdl name space func() string { return g.wsdl.TargetNamespace } which is incorrect, as it should be returning the schema
