30.10.22 relative path [fs.def.rel.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]
