530		* Depending on which components of the URI are present, the resulting
531		* string is either a full URI or relative reference according to RFC 3986,
532		* Section 4.1. The method concatenates the various components of the URI,
533		* using the appropriate delimiters:
534		*
535		* - If a scheme is present, it is suffixed by ":".
536		* - If an authority is present, it is prefixed by "//".
537		* - The path can be concatenated without delimiters. But there are two
538		* cases where the path has to be adjusted to make the URI reference
539		* valid as PHP does not allow to throw an exception in __toString():
540		* - If the path is rootless and an authority is present, the path is
541		* be prefixed by "/".
542		* - If the path is starting with more than one "/" and no authority is
543		* present, the starting slashes are be reduced to one.
544		* - If a query is present, it is prefixed by "?".
545		* - If a fragment is present, it is prefixed by "#".
