  25 ;; Test cases covering URI reference resolution as described in RFC3986,
  26 ;; section 5. Reference Resolution and especially the relative resolution
  27 ;; rules specified in section 5.2. Relative Resolution.
  28
  29 ;; Each test calls `url-expand-file-name', typically with a relative
  30 ;; reference URI and a base URI as string and compares the result (Actual)
  31 ;; against a manually specified URI (Expected)
