It is indeed not part of any standard. It was originally a Mozilla vendor extension, later copied by Opera and Safari. We added support for it in 2002 because at least at the time, some sites used it: http://trac.webkit.org/changeset/2940

It should probably be added to a spec at some point. Perhaps Web DOM Core could be expanded to cover Range & Tranversal?
