What's wrong with namespaces? These are simply globally unique identifiers that allow us to define and use our own globally unique names and make them passably human-readable. That is: <a:log /><b:log /><c:log /> can mean a math function, a text file that records what's happening, and a cut-off trunk of a tree and there will be no confusion whatsoever. (I really don't get how SOAP is relevant here.)
