Date: Sun, 16 Aug 2009 19:33:27 -0700

On my Windows emacs, when i open a xml file, the default mode loaded is 
sgml-mode, not nxml.

This is reproducible with Emacs -Q with FSF's binary for Windows.

Since nxml is better, it seems the default should be nxml-mode.

PS here's some tidbits from Lennart.

I'm not sure how emacs choose modes, or the policies, mechanisms, file 
locations...etc, or what majmodpri.el is supposed to do. Anyway, i thought 
this warrant a bug report for the record. Thanks.

Major modes are choosen by searching auto-mode-alist etc. The first
hit is choosen. (Sometimes the lists are searched several times
though.)

majmodpri.el sorts the list so that the major modes (or multi major
modes) that the user prefers comes first.

When we offer several different modes for the same language
(e.g. perl-mode vs cperl-mode), we should try to make auto-mode-alist
(and other such facilities) point to a function alias (e.g. html-mode)
which can then point to whichever major mode the user favors.

E.g. we should probably rename sgml-mode.el's html-mode to
sgml-html-mode, and then make (defalias 'html-mode 'sgml-html-mode) so
that the user can easily (fset 'html-mode 'my-html-mode).

That is a good idea, but I would suggest using a table in between
instead of fset.

And a simple way to manipulate that table. (Maybe putting a property
like 'this-is-a-major-mode on major mode functions?)

In Bug#4169, it's been suggested to default to nXML mode for editing XML
files.  Does anyone on this list support or object to this?  I don't
edit XML files, so I can't form an opinion on this.

I support it -- nxml is an _excellent_ mode for editing xml files,
mostly because it does real-time verification.

Nxml has been my default xml editing mode for years, so yes.

I've made nXML mode the default for editing XML files.
