Making [[Template:Doc-apihelp-param]] translatable

Hi there, I'm trying to replace the content in Template:Doc-apihelp-param with Template:Localized in order to make it possible to translate it to other languages, since other templates (Template:Doc-singularthey to name one) used in documentation pages allows this. I wasn't successful in my (two) attempts, since the bullet list that follows "For other messages relating to this module[...]" won't display, so now I'm asking for assistance. The problem seem to lie in the fact that the some parameter values, like params, won't pass to the sub page I created for the English translation (Template:Doc-apihelp-param/en).
