Section 7.1.8 says:

   Description:
    Specifies if the Application ID is based on peer-to-peer
    technology.  Possible values are { "yes", "y", 1 },
    { "no", "n", 2 }, and { "unassigned", "u", 0 }.

It should say:

    technology.  Possible values are { "yes", "y", 1 },
    { "no", "n", 2 }, and { "unassigned", "u", 0 }.

    Note that 0, 1, and 2 above are integer values; as UTF-8 
    characters they are U+0000(NUL), U+0001(SOH), and U+0002(STX). 
    WARNING: the overloading of a string value with an integer 
    representation that can take the value 0 requires careful 
    handling on collectors and exporters which use this value
    to signify the end of a string.

Notes:

Added clarifying text. The difference between a quoted and unquoted
digit (1 vs "1") is extremely subtle and easily missed.

See, for example,
http://www.ietf.org/mail-archive/web/ipfix/current/msg07151.html.
