High Venu, I'm not suggesting getting rid of the DOM API but I think that there are domains that will work faster and slimmer with a Stax/SAX API than with DOM API(WS mainly and perhaps j2me), I was suggesting doing something similar to what I suggest in here http://issues.eu.apache.org/bugzilla/show_bug.cgi?id=32657 I have blog about my ideas in http://r-bg.com/apache . But some other seems to get to the same point as me(It seems after published after my blogging but I think they gets there indepently, it is a obvious solution indeed) http://www.cs.indiana.edu/~welu/c14n_hpdc05.pdf So. I think that we shall provides to APIs for the signature creation/verification (not just c14n) one for trees and other for streaming. What do you all think? > Regards > Venu > > -- http://r-bg.com
