Hi Michael Thanks for the report and digging into the actual XML documents that are sent.
It turns out that if I remove the redundant namespace definitions and just use a single one on the <SimpleSearch> node, all is apparently fine. I've put a pre-release version of the SSOAP package that does at http://www.omegahat.org/Prerelease/SSOAP_0.9-1.tar.gz You can try that. I'll release this version when I also fix the issue with XMLSchema that causes the error in genSOAPClientInterface() BTW, the if(!is.character(token)) in the example in chemSpider.R is an error - a mixture of !is.null() and then checking only if it is a character.
