ASSUMPTIONS

   1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
   sign (-), and period (.).  Note that periods are only allowed when
   they serve to delimit components of "domain style names". (See
   RFC-921, "Domain Name System Implementation Schedule", for
   background). ... 

Clearly written to accommodate the state of the DNS at that time, and even
though the current DNS standards postdate RFC 952, 952 has not had to be
updated to cope.  And from RFC 1123:

    2.1  Host Names and Numbers

      The syntax of a legal Internet host name was specified in RFC-952
      [DNS:4].  One aspect of host name syntax is hereby changed: the
      restriction on the first character is relaxed to allow either a
      letter or a digit.

So what you want to define as the "real" standard takes all but one item
of its definition from RFC 952.

What's the point you're trying to make?
