I found out that Microsoft released another whitepaper around BizTalk Server recently than the one from Dennis Mulder. There is an other around troubleshooting SOAP adapter in docx format.
Microsoft® BizTalk® Server uses the SOAP adapter and orchestrations to receive and send Web service requests. The SOAP adapter enables orchestrations to be published as Web services and consume external Web services. Because configuring and/or using Web services can be complex, BizTalk Server handles many of these complexities on behalf of the user. Even so, there are still issues arising from time to time. This white paper is designed to highlight common issues and to provide guidance for how to resolve them.
Another good resource :)
