Just to be clear:
* tabs -> tabset
* pane -> tab
* pane-heading -> tab-heading
* ... -> tab-pane  (or tab-body)

So the nice thing then is that everything starts with tab (or bs-tab) so it is easy to see that they are all related (you could even go for tab-set for super convergence).  The only additional item is tab-pane/body, which I can live without but just thought it made the mark-up clearer.
