RFC 1035 did not change the definition of a hostname in any
way shape or form other than reducing the *effective* maximum
hostname length to 253, that being the maximum length that
can be encoded on to the wire.

The root label takes up one octet and the length of the first
label takes up one octet.  The rest of the lengths are matched
by period.

The suggested name sytax is just that *suggested* along with
instructions to check the relevent RFC's for what is legal
for a particular purpose.
