Re: html, css, and js modes working together

[Stefan Monnier]

Regarding the mode's name.  You could rename html-mode to html-only-mode
(or html-basic-mode?) and then use html-mode for that new mode.
Ideally, you could even make html-only-mode a parameter so that your new
html-mode could be used with other "basic" html editing modes such as
nxml-mode or psgml-mode.

This looks good.

The use of buffer-local-variables+progv should make this unnecessary.

FWIW, I think that html-mode should not belong to any html mode package
in particular (maybe it should use `define-alternatives`).
