I've added 207 as a valid PROPFIND result, so this should be fixed, but
will probably fail later on (I never tested it with DAViCal).

That part was deemed to hackish and fixed in another way.

You cannot use that hacked url-dav together with newer Emacsen.

Please try the latest org-caldav version and let me know how it works
(on GitHub please, since this doesn't affect Emacs development).
