The <octetstring> rule isn't actually defined anywhere so we're
free to define it to be something sensible. I suggest we make
it a hexadecimal string.

Note that the 4th edition of X.500 has deprecated this syntax.
The X.500 working group has even gone to the extent of removing
the teletexTerminalIdentifier attribute from every object class
that used to reference it. An option for us is to throw it out too.
