I assume that there should be no serious implementation issues, provided that the correct procedure described in section 2.2.1.2 is followed.
Furthermore, some implementation request that value "g" be manually assigned/specified.

This errata aims only to correct the description to keep text, formula and procedure consistent, and to avoid confusions.

Regards,
Charlie

I am aware of an implementation that was done 17 or 18 years ago.  I do not know if it is still being used.
