      ABNF:


   key-s-tag        = %x73 [FWS] "=" [FWS] key-s-tag-type
                       0*( [FWS] ":" [FWS] key-s-tag-type
   key-s-tag-type   = "email" / "*" / x-key-s-tag-type
   x-key-s-tag-type = hyphenated-word   ; for future extension

Isn't there a missing right parenthesis in the continuation line of
the key-s-tag production? IMHO, it should be:

   key-s-tag        = %x73 [FWS] "=" [FWS] key-s-tag-type
                       0*( [FWS] ":" [FWS] key-s-tag-type)
