    787788   This specification adopts the definitions of "URI-reference", 
    788789   "absolute-URI", "relative-part", "port", "host", 
    789    "path-abempty", "path-absolute", "query", and "authority" from the 
     790   "path-abempty", "query", "segment", and "authority" from the 
    790791   URI generic syntax. 
    791    In addition, we define a partial-URI rule for protocol elements 
     792   In addition, we define an "absolute-path" rule (that differs from  
     793   RFC 3986's "path-absolute" in that it allows a leading "//") 
     794   and a "partial-URI" rule for protocol elements 
    792795   that allow a relative URI but not a fragment.
