Is it possible to see if a web service uses SOAP 1.1 or 1.2, based on the information in the WSDL?

I have found this page
http://schemas.xmlsoap.org/wsdl/soap12/soap12WSDL.htm
which says that Soap 1.2 uses the new namespace http://schemas.xmlsoap.org/wsdl/soap12/
It is in the 'WSDL 1.1 Binding extension for SOAP 1.1'.
Yes you can usually see what SOAP version is supported based on the WSDL.
Take a look at Demo web service WSDL. It has a reference to the soap12 namespace indicating it supports SOAP 1.2. If that was absent then you'd probably be safe assuming the service only supported SOAP 1.1.
