What RFC are you reading? Some kind of a "fixed" version of RFC 2616?
RFC 2616 does not have the above definition for subtag. RFC 2616
errata[1] mentions that subtag definition should be relaxed and quotes a
new definition from RFC 3066:

	subtag        = 1*8(ALPHA / DIGIT)
	
That quoted definition uses the "/" separator because RFC 3066 is using
ABNF, a different BNF notation. When the errata is integrated into the
next HTTP/1.1 RFC, the notation needs to be corrected (either in the
quoted fix or everywhere else).
