Ahh.... That's exactly what I was looking for. The documentation mentions that XOTcl is built on Tcl namespaces, but is a little vague in exactly how, aside from the discussion of aggregation. And I'd managed to overlook the documentation for the "requireNamespace" method. Actually, even after seeing your example, I don't think that the current "requireNamespace" method documentation is quite clear as to why it's needed. May I suggest adding a sentence or two to its description basically outlining an application of it, such as this, to help other newcomers to XOTcl understand its use?

Thanks for the clarification!
