Hi all, continuing with today's discussion on prefix rewriting I wanted to bring up the prefix-free canonicalization we published last year (ACM SWS 2009). The approach basically consists in rewriting every XML element to a representation like this: <localname xmlns="namespace-uri"> This way, you don't need prefixes at all (besides for the attributes), the resulting XML is still well-formed, there is no "unsigned" information besides the prefix name, and you don't need doing digests+base64 stuff nor excessive search for predefined prefix mappings. Maybe we could consider this as one option for the rewriting parameter. Bigger example: <nsA:A xmlns:nsA="http://A.ns" xmlns:nsB="http://B.ns"> <nsB:B> <nsA:A2 /> </nsB:B> </nsA:A> becomes sth. like <A xmlns="http://A.ns"> <B xmlns="http://B.ns"> <A2 xmlns="http://A.ns" /> </B> </A> In order to optimize performance one could suppress the xmlns=".." output if it would be identical to that of its parent element. However, this again may become a source of confusion. What do you think? best regards Meiko
