Info Directory: What counts as an editing mode?

[Stephen Berman]

I've finally finished the Texinfo manual for Todo mode and am ready to
install it, but first would like clarification about where to put the
Info dir entry.  The natural place would seem to be in the section
"Emacs editing modes", but there are several entries in the "Emacs misc
features" section for packages that seem to be primarily used for
editing (in some sense): Autotype, EDT, Forms, Remember, VIP, VIPER.  So
where should I put the entry for Todo mode?
