In OSB can you change the proxy service or business service WSDL using a Customisation File?
if so how?
I think I worked it out myself:
<cus:externalReferenceMap>
<xt:oldRef>
<xt:type>WSDL</xt:type>
<xt:path>ProjectName/wsdl/MyWsdlNameOld</xt:path>
</xt:oldRef>
<xt:newRef>
<xt:type>WSDL</xt:type>
<xt:path>ProjectName/wsdl/MyWsdlNameNew</xt:path>
</xt:newRef>
</cus:externalReferenceMap>
