application/xml is recommended as of RFC 7303 (section 4.1), but text/xml is still used sometimes. You can assign a specific MIME type to a file with .xml extension depending on how its contents are meant to be interpreted. For instance, an Atom feed is application/atom+xml, but application/xml serves as a valid default.
