I hacked together an XML Fragment Interchange server last year, and put on a "bubble down" and "bubble-up" option on it: the former put all namespace declarations at the top, the second kept them local. For example, if someone is cutting and pasting a section of a document, they should bubble down any higher-level declarations which are needed to the node being cut. Cheers Rick Jelliffe
