Rapha and Sven: Thanks for bringing the xdg-list to my attention; let's move further follow-up discussion there. Rapha: Thanks for your comments - I've already considered some of those issues a bit, but you're right, they need to be addressed in the proposal. I'll work on it.

Point conceded - I hadn't considered the case of one application making use of thumbnails that only other applications can generate. Thanks. Bryan
