	A scheme consists of a sequence of characters beginning with a letter and followed
	by any combination of letters, digits, plus (`+`, period (`.`), or hyphen (`-`).

	Although schemes are case-insensitive, the canonical form is lowercase
	and documents that specify schemes must do so with lowercase letters.
	It is followed by a colon (`:`).
