Arguments: string-or-uri &key (class 'uri)
If string-or-uri is a uri instance, return it unmodified. If string-or-uri
is a string, parse it into a URI object. Escaped encodings of the form
%<hex><hex> are properly converted into single characters. The class
keyword allows creation of subclasses of uri.
If the result is a URN (that is, an object of class urn),
urn-nid and urn-nss
access the Namespace Identifier and the Namespace Specific String of the URN.
