SVG 1.2 ...

Hello,

Due the research of requirements for a viewer for SVG 1.2 I wanted to
ask a few questions.

1.) Will SVG 1.2 be a recommendation in Jan 2005 (like in the roadmap)
or will it take longer?
2.) When could someone start an implementation of SVG 1.2 to be sure
there're no more changes in it
3.) I'm still pretty confused with RCC vs XBL. What exactly is XBL (some
code sample would be really nice) and how does it compare with RCC? Will
XBL replace RCC? When will the draft reflect that change?
4.) I'm not perfectly into SVG 1.2 but afaik it supports a socket modul,
right?
5.) How's Xpath-Selection done in SVG 1.2 (e.g. with javascript to
select an element) or is that not allowed?

Thank you so much for answering these questions.
I'd really appreciate long and detailed answers to let me get into it
and finish my research.

thanks,
Alexander
