In the BizTalk Server 2009 documentation for the topic How to Handle Typed Fault Contracts in Orchestrations, the documentation assumes the reader is calling a web service based on the SOAP 1.2 specification.  The code sample presented will not work if the user is configuring a WCF Send Adapter to call a web service based on the SOAP 1.1 specification.  When the code sample is used as it is presented against a service based on the SOAP 1.1 specification, the user will most likely see an error like System.InvalidOperationException: Unable to find match for inbound body path expression.
