Gervase Thanks for the tip - I like the idea of using a relation here. Non-rendering is a downer (yes - I know - don't tag for the renderers) but sounds like some Good Samaritans have it in hand. If fully and universally implemented, this solution - which I feel is technically the right one - would create a huge number of new relations (a lot of bridges in the world!) - is this a problem anywhere in the software chain?
