Oh, I didn't mean to include an example of a function, but just when to
set 'formatexpr' to an existing function. And where to do that. I
would assume in most cases it would be done in the ftplugin file:
:set formatexpr=xmlformat#Format()
With an explanation of how Vim finds the file that contains the function
in the autoload directory.
Fixing the problems in Insert mode is a different issue.
