It already does, a couple paragraphs above the stuff you quoted:

     The format of a cron command is very much the V7 standard, with a number
     of upward-compatible extensions.  Each line has five time and date
     fields, followed by a user name (with optional ``:<group>'' and
     ``/<login-class>'' suffixes) if this is the system crontab file, followed
     by a command.
