The baseURI is only required it there are partial URIs. If every URI in a document is either a either fully qualified URI, or a namespace-abbreviated URI, including the Ontology declaration, then any definition of or assumptions about the baseURI is superfluous. Everything is explicit. That should be enough for any application. So I guess I don't understand the question
"how could TopBraid possibly make sense of it" My other point is that if TB is relying on extra information being smuggled in comments, then we are well out on a limb here.
