normalize-uri-name String String

The `normalize-uri-name` function normalizes the string argument by adding a uri scheme if missing in the original string. If the function detects that the name starts with a host name, the "http" scheme is added. If the function detects that the string starts with a path, the "file" scheme is added. otherwise, the name argument is left untouched.

system-uri-name String String

The `system-uri-name` function normalizes the string argument by prioritizing the system name. The function attempts to find a file that match the sring argument and eventually build a uri file scheme. If the file is not fond, the normalization process occurs with the `normalize-uri-name` function.
