and that reference (rfc 1035) is pretty clear, section 3.3.14

    TXT-DATA        One or more <character-string>s.

Each <character-string> is (section 3.3 of that same RFC):

    <character-string> is a single length octet followed by that number of
    characters. <character-string> is treated as binary information, and can 
    be up to 256 characters in length (including the length octet).

I only have the 3rd ed. of "DNS and BIND" so I can not verify your claim
it (wrongly) tells the maximum is 2K. The maximum is the max length of the
rdata, which is 64K.
