;; section 3. Syntax Components and 4. Usage. See also appendix
;; A. Collected ABNF for URI, as the example given here are all

;; Each tests parses a given URI string - whether relative or absolute -
;; using `url-generic-parse-url' and compares the constructed
;; URL-struct (Actual) against a manually `url-parse-make-urlobj'-
;; constructed URL-struct (Expected).
