 The second query works because 'Document' is the name if the 
element... If you use local-name() instead it wont work anymore.

You're facing a faq about XPath and default namespaces : there is no 
default namespace in XPath. So if you want to select a namespaced 
element, you must bind the namespace's uri to a prefix and use it in 
your xpath expression. It doesn't matter if your document is using a 
default namespace or a prefix.

So try something like : xmlXPathRegisterNs(xpathCtx, BAD_CAST 
"urn:ssp.pm.GetAccount$camt.003.001.02", BAD_CAST "ssp");
and the query : /REQUEST/RequestPayload/ssp:Document

And also, your document uses a prefix that is not declared :
t.xml:10: namespace error : Namespace prefix SwInt on RequestPayload is 
not defined
     <SwInt:RequestPayload>
