One possibility is to remove the reference to RFC 1951 completely.

  deflate
    The "zlib" format defined in RFC 1950 [31]. 

This variant keeps both RFC 1950 & 1951 but drops the troublesome labels.

  deflate
    The compressed data format defined in RFC 1950 [31] in combination with
    the compression mechanism described in RFC 1951 [29].

Indeed - the choice of name is the source of the ambiguity - there are two
conflicting uses of "deflate" in the definition. If 2616 had used "zlib"
instead of "deflate" the problem wouldn't have happened.
