Richard Hills:

Under the ABF Alert Regulation, all calls are either "conventional"
or alternatively "natural".  A "natural" call is defined as "not
conventional".  A "conventional" call is defined as per Chapter One
of The Fabulous Law Book.

The English Bridge Union takes a more nuanced approach, since the
EBU is wary of the flaws in the 1997 definition of "convention".

The word "convention" or "conventional" frequently appears in the
1997 edition of the Laws.  However, reference to an "artificial"
call also appears in the famous Law 75 footnote.
