The easiest way, for functions, would be to define them with a ! as
you show in your example. Are you sure the ! occurs in all the
functions in your file?
For commands, you could do the same (use command! instead of command)
or you can pass it the "-buffer" argument to only define the command
on a per-buffer basis. The latter is probably better anyway, as you
don't need to be able to use the command in an xml file you open, for
example.
