27.10.4.19 relative path [fs.def.relative-path]

A path that is not absolute, and as such, only unambiguously identifies the location of a file when resolved ([fs.def.pathres]) relative to an implied starting location. The elements of a path that determine if it is relative are operating system dependent. [ Note: Pathnames “.” and “..” are relative paths.  — end note ]
