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