Robert, Thanks again. I can see how I can acheive what I want to acheive with simple_tag.
I'm not sure that I understand your first example though. Is the list of url patterns passed as parameters to inclusion_tag supposed to be searched for a match to decide which template to use? It seems I have to pass the values to complete the patterns in the context. I'm not sure I understand how I'm supposed to get them there - through the view of the parent page? from a separate template tag? It all seems kind of complicated - which given the elegance of what you've produced so far, suggests I've misunderstood something. In short, I'm confused. Would you care to elaborate? Thanks.
