Lisp, siod and LyX

Hello I am writing so to speak as a mediator between the maintainer of the LyX program and the xemacs maintainers. There are 2 points worth to be discussed. 1. LyX is written in C++ (I don't know any details) and now the maintainer is looking for an extension language available as a library! The decision is not made yet but Siod another lisp dialect is considered very seriously. Now I proposed, xemacs-lisp, which would may be allow to use a lot of already written extensions and also open the possibility to benefit from the huge amount of xemacs-lisp experienced people . However I have no idea about the xemacs-lisp implementation in the C code and that's why I try to contact you, or some of the persons who figure as maintainers. 2. I am interested in this because the second step of LyX concerns internationalisation beyond iso-8859-1. So if xemacs-lisp would be a candidate for the LyX team, Mule could be chosen for the purpose of internationalisation. Pls if you are willing to give some helpful information the persons interested in these questions would be grateful. If you want to contact the maintainer of the LyX project by yourself here is his email address: larsbj(a)lyx.org Regards Uwe Brauer
