Thanks for your response and sorry for being unclear.  Let me rephrase
that: The idea is to pass the type of a new float-env to AUCTeX as a
TeX-comment enclosed in braces, e.g.

--8<---------------cut here---------------start------------->8---
\usepackage{newfloat}

\DeclareFloatingEnvironment[
  name=Code,
  listname={List of Codes},
  fileext=lol]{code}  %  {verbatim}
%                     ^^^^^^^^^^^^^ {verbatim|figure|table}
--8<---------------cut here---------------end--------------->8---

I am looking at everything following the `{code}'.  My current
definition fails if a user does something like:

--8<---------------cut here---------------start------------->8---
\usepackage{newfloat}

\DeclareFloatingEnvironment[
  name=Code,
  listname={List of Codes},
  fileext=lol]{code}
%                   ^ no `{' after this point
--8<---------------cut here---------------end--------------->8---

I hope it is more clear now.

Best, Arash
