Does anyone know or has an opinion about the use of the 'X' in e.g.:

	- planet X 	(possible tenth planet of our solar system)
	- agent X	(secret agent)
	- generation X	(book about 'lost' generation of the 80's (?)
			 author: D. Coupland)
	- XL		(extra large)
	- X-files	(FBI's secret files)
	- X factor	(Iron Maiden's last album)


Next to X=ten and X=extra, the 'X' expresses something mysterious or
secret. Does anyone know other examples?

Thanks in advance!
