I can confirm this. The SOAP they're talking about here is not the SOAP we're using in the XML world. It's really confusing, the new SOAP is a re-use of something that died inside Microsoft. They liked the name, and wanted to use it for something important. Another clue is the date on the submission, in November 1997. Work on SOAP, as XML-over-HTTP, the protocol in use today, didn't start until March 1998. Further, before we announced SOAP, I asked Microsoft if they had filed a patent on it, and they said they had not. This was a material concern for us. We didn't want to endorse something that Microsoft had patented. Another large software company told us they were sure that Microsoft *had* filed a patent. I suppose we have just a few more months to find out for sure one way or the other.
