    No answer, here?

Did we ever discuss this?  Anyway, I believe it's a specific hack for Elisp:
(defun foo arg1 &optional opt1 &rest r
==
@defun foo arg1 &optional opt1 &rest r

I guess Philippe (or whomever) decided to translate that as <defparam>.

Personally, I'm not sure it's possible to rationally parse the arguments
to @defun.

    Should @top be used if there is none of 
    @settitle @title @shorttitlepage @titlefont (I don't know)?

Sounds fine to me.

    and if there is no title should there be a warning if producing html 
    (I believe so)?

Sounds fine to me.

Thanks,
