For what it's worth, Zitao is correct.

RFC 7322 §1:

    The world of technical publishing has generally accepted rules for
    grammar, punctuation, capitalization, sentence length and complexity,
    parallelism, etc.  The RFC Editor generally follows these accepted
    rules as defined by the Chicago Manual of Style (CMOS) [CMOS]...

CMOS 15th ed §7.89:

    "When the second part of a hyphenated expression is omitted, the
    hyphen is retained, followed by a word space.

    "/fifteen- and twenty-year mortgages/

    "/Chicago- or Milwaukee-bound passengers/"
