skeleton improvement

Hi, I am writing a minor mode for having "holes" in your buffer that you can fill by different means. I would like to interface it with skeletons, and I am not able to get interesting positions after a skeleton has been inserted. In Emacs there is this variable 'skeleton-position which is made for this (added recently it seems). Moreover one can define in the skeleton what are the positions which should be added to this variable. My question is: is it possible to have such a variable also in XEmacs please? Sorry if this is not the right list for this kind of question. Pierre Courtieu
