xml functions

Hi! I've added description for: $parser, $prefix, $uri, and other attributes in these xml functions. I've saved as patches for review, and I've reported 2 bugs in: xml-set-start-namespace-decl-handler and xml-set-end-namespace-decl-handler but I can't to commit the files because I don't have enough karma. I'd like if anyone would can to review it, thank you very much :) Regards Carlos
