Does http://www.jabber.org/jeps/jep-0174.html#txt say that it is required?

If so, I think we should change that. IMHO all the TXT records should be
optional except for "status".

And in practice (i.e., in iChat) I have seen people not set the 1st and
last fields, so I don't think they are really required. See also:

As Justin notes, JEP-0174 is intended to provide canonical documentation
of link-local presence and the XMPP-like messaging that is enabled by
use of the _presence._tcp.local. service. But JEP-0174 does not document
other forms of communication that are enabled by zero-configuration

You are right -- it is not necessary and I don't think the JEP says it is.
