I've changed my opinion on this. I do think XPath and XPointer can serve
to bring to the topic map engine the portions necessary to implement
TMQL. In other words, TMQL can be built as a layer on top of an XPath/
XPointer engine. If this is not true, we're in trouble.

As for thinking differently, I pride myself on that, thank you very much.
